  I have purchased 8 ******** Escalades in the last 5 years this last one was bought on 08/29/2024 I have had to call Onstar now 6 times to be told that Tech Support needs to review and will call me in 3-5 days within 3 days the app starts working again then drops connection with my SUV as much as I have spent on these SUV you would think you would get better service from OnStar or ******** but nope they just tell you they will work on it and get back with you never happens and then when you call again they say we cant help you this is Tech Support!! Just crazy how they act like NO BIG DEAL but I have paid for the plan and SUV for things not to work correctly.. Makes me think twice on buying a **/******** ever again

  Cancelling any OnStar service requires your ************ called their service line to cancel an OnStar plan.The "my chevrolet" phone app will not allow you to cancel the service but only to add one!Therefore you are required to call them.They asked for :1. my full name 2. VIN 3. phone #4. home address 5. email address This is super ridiculous! Why do they need all this information just to cancel a plan?? They stated they needed all of this information to protect me from scrupulous people! i think OnStar itself is very scrupulous!!Sirius XM is the very same way! You can add their service very easily but to cancel requires you to call an agent who will try to talk you out of it!OnStar needs to change their procedure of cancelling a service w/o requiring all of the above information! I think their current method is a way of making it uncomfortable & difficult for a customer to cancel a service!!

  Took an hour to cancel my service and when I tried to get a refund for a charge that processed the day before I was informed that due to them billing for the previous month and not the current month, I was not able to get one. No where when I signed up for this service do I recall that being said. *************** and garbage billing policy.

  This company is a greedy low-level sack of c*** They will continue to charge you after you have called and messaged about cancelling your service, even when you receive a confirmation number for the cancellation. DO NOT USE THIS SERVICE.

  Renewed OnStar yesterday. We are traveling from ******* to **************. We pressed our OnStar button to get driving directions at 4 am. The recorded message said we were being transferred but then just kept beeping with no answer. We tried this for about 10 minutes. Then tried calling and no answer. We tried texting and the text said sorry you are having this problem and suggested we try the OnStar button again and or try to call? Seriously! If I wasnt so made I would laugh. So its now almost 8:30 am. Than goodness for our phone providing us directions because OnStar is useless! They should be fined for taking peoples money and providing zero service.

  I got the service when I boutg my car from the dealership. Its a service I never used and tried to cancel after the free trial service. I used the call button in the car and got a rep on the line . I asked him to cancel service and he said he had done that., Now 8 months later they are still billing me $39.99 a month. I finally got it cancelled(I hope) after 20 minutes on the phone with Onstar.

  Truck was stolen and I contacted ONstar to disable the vehicle but they would not do it. I guess they thought I was lying to them even though I gave them all information. So I paid for years for a service that acts like it is there to protect you and your vehicle. But when actually needed does nothing to help. They don't even track the vehicle for you to help find it. Waste of money!

  On November 28, 2023 I received an email for a black Friday deal, get 5 months free of the essentials package plus a free ***** egift card. On December 1, 2023 I called the their customer service number to inquire when and how the e-gift card worked and when i would receive the egift card. The advisor i was on the phone with canceled the plan i personally did online without asking me or telling me what she was doing. I received an email right after she did that while i was still on the phone with her and i asked her why she did that, she stated i did the wrong package, I assured her i did not, I sent a screenshot of the confirmation email I received after i purchase the package and than took another screenshot of the email i received after she did it, they both said the same exact wording except the dates were obviously different so she prolonged me getting the ***** egift card. I have since than called back more than 10 times trying to figure this egift card out. They continue to tell me they have escalated this issue to their supervisor or give it 24-48hrs or 3-5 business days and i should receive it, The last supervisor that was taking care of this issue told me if i did not receive a egift card in my email with the link in 3-5 business days to call back and she would provide me with the link. I call back and continue to get the same run around with 24-48hrs, 3-5 business days etc...It's so frustrating to call a business when no one has any knowledge of anything so their responses are always the same with no resolution. They always say they will follow up with me on this day or that day and they never do. I normally call back myself and they still have no resolution to the issue. I have never had such poor customer service from a company that has so much business for something that is installed in all of our new vehicles but no knowledge of their own product they advertise.

  Tried to cancel their service and called their *****- onstar phone line which is outsourced to *****. Couldn't understand the person on the line and they would not cancel my service. Would not confirm that they were with Onstar and that on the 'recorded line' would not confirm that they would cancel my service. . . Kept asking for my credit card information which they had on file and had just charged my account three days before I called. Then, after I confirmed my credit card information on file - they asked for a different credit card and said that their system wasn't taking that card number?? Why do they need a credit card number to CANCEL? Seemed like a scammer so I hung up and went to my ***** Corvette and pushed the Onstar button. A nice lady from ******* answered and in minutes cancelled my service, refunded the recent charge and set up for a free 3 months next summer. Onstar needs to fix their 888- onstar service! Quit outsourcing jobs!
