Ive reached out several times since my initial contact and have not received a response. My ticket number for reference is #******.

    I purchased several items from ****** on January 12,, 2025. This included two Airmega replacement filters which it turns out are the wrong size for my particular Airmega model. I contacted ****** multiple times via email and only heard back once, on February 3, 2025 stating that they would have to have a management meeting to decide whether or not to refund me! Seriously? I have never heard of such a thing in all of my years! They also have failed to reply to subsequent emails. ****** obviously has no intention of refunding me at all! This company is highly unethical! I want a return label to send back the incorrect item and a refund.

    I have tried to return two products I purchased within the return period. The customer service *** did not allow me to do a return. Returning from order #******. Two 400s units *********** 1: 15102DNO22A2100351 Sn 2: 15102DNO22A2100348 Reason for return. Product specification shows the 250s is louder on setting 3 at 54db and the 400s on level 3 is 52. I have 4qty 250s units and they are noticeably quieter than the 400s. Either the specs are wrong or these units are defective. I dont believe I should be charged for returning the units when they are not working as advertised. I like my 250s units and plan to purchase 2-4 more to ***lace the 400s I am returning.I would like a return authorization for both units and a label to ship back and a full refund.I emailed the company on 1/23, 1/24, 1/27 and 2/1 attempting to resolve.

    I need to cancel my contract because I was so scared and suffered mental trauma due to the behavior of a Coway employee who yelled at me got an angry on January on 8th.After the water purifier installation technician visited, the Coway employee yelled at me and got angry, I was so scared at that moment that I politely asked him to stop yelling and getting angry that more than three times, but he did not accept the request. I told the Coway employee several times that I was scared. He was still yelling, and he shouted at me, "if you're scared, call the police". I was even more scared, and my hands were shaking. so, I immediately called the Coway service center and asked help, but I did not receive any help. I cried because I had severe mental trauma that day when the Coway employee visited my house, and I could not sleep for several days. Even now, I think of that scene every time I go into the kitchen, and it is difficult. so, January 9, I called the Coway water purifier company and told them the details of the incident and requested cancellation. However, Coway told me that I would have to pay cancellation penalty. I brought it all the way from ********** to ***** for use as a water purifier, but I was scared by the installation technician's yelling and angry, so I requested to cancel it. because of the mental pain and psychological trauma, I got from the Coway employees on January 8th. I was shaking my hands and crying the day the installation technician visited, and I remember that day and am suffering from psychological trauma. I still have a hard time because I can't forget that day. It's especially hard every time I go into the kitchen and see the water purifier. It left a big trauma for me. My heart aches so much. I want to cancel without penalty. Please help me. I hope I don't have to see the water purifier again soon. Even now, I'm trembling with fear when I think about that day. Thank you for reading my story and for helping me.

    Hello, I was charged a late fee by this company three times. I have called them to clarify that my bank account had sufficient funds every time that they charge my card. My card gets charged twice a month during the 1st and the 15th. Its been repeating that they keep stating that 15th the card does not have enough funds. And I called them on the 17th so that they can charge again but they kept telling me me I didnt have funds once more. While on the phone I checked my bank and asked them to charge my card but they offered a discount offer. However I am wanting my fees returned

    A year after my Coway countertop *********** purifier rental stopped working, I contacted Coway to request a technician to service the device. The ***resentative mentioned that she will have an English speaking *** call me back, but no one called me back. I called back a week later and was informed that a local technician will reach out to me. I waited two weeks and did not hear back from a technician. So I called the customer service department at the end of April requesting the status of the ***air, but due to a language barrier I could not interpret what was being communicated to me. With the machine not working and no call back from a technician, I decided to just cancel the service and return the device. I called ********************** and was told someone will call me back. Again, I did not receive a call back. I followed up several weeks later and was informed that my account *** will call me back. No call back! This ***eated every month for 6 months! And every month I'd receive a "final notice bill" in the mail. Despite numerous attempts at contacting Coway to discontinue service and to pick up the device, there has been no follow up from Coway. I have been stuck with an inoperable machine for almost 8 months now with no resolution from Coway, and now my account is in collections. It is not reasonable to hold me accountable and to send me to collections when I (numerously) requested to discontinue service on an inop machine 8 months ago.

    We currently rent a water filtration system from Coway. Since January, this machine has been serviced three times. Once in January, June and July. The machine again is having issues and we called last Friday 09/20/2024. They expected us to wait a week, 09/26/2024, for a technician to come out to evaluate the machine. Today has come and the technician went to the hospital and they are expecting us to wait to 10/01/2024. This isnt a machine that dispenses some Unnecessary drink. We are talking about water which my family needs, especially our one year old boy. When trying to talk to them about cancelling the service they refuse to and are stating there are exorbitant fees to cancel. Please contact me for the whole debacle.

    We are signed up for a monthly lease of this company's water purifier, and the lease includes regular maintenance and filter changes---our last filter was changed on March 7th, 2024. About 2 weeks ago, our water started to taste increasingly weird, almost like sewer water. Last Wednesday, on August 28th, I contacted the local customer service department to report the problem and to ask them to please help us get the filter changed sooner---by that point, we were already buying water from the grocery store because the water taste was so bad. I was assured that somebody would be in touch. By Friday afternoon, August 30th, nobody had contacted us, so I reached out to customer service again. I was told that the first representative did try to have someone call us, but nobody did, so this second representative assured me they would try again. Today, fully one week after I made my first call, I still did not get a reply from anybody. So I called again at around 11:30. By 4pm, nobody called us back. So I called again, and this time I got very upset. Finally an hour later, I received a call from our ****** (aka service technician), who will be stopping by today. This is a relief, HOWEVER, it is totally unacceptable for a paying customer to call customer service multiple times over the span of a week and have to resort to anger to finally get any kind of response. Also, there was no explanation given as to why nobody was able to contact me sooner. I actually wanted to email the CEO of Coway USA, but unfortunately leadership's contact information is not found online, so this is my way of telling Coway USA that they need to train their customer service and/or technicians better, to take customer complaints seriously, and provide a TIMELY response, with some sort of explanation and rectification of the situation.
