I took a brand new pair of shorts in to their store and spoke with a nice woman about altering them. She was very confident that they could do the alterations, so she gave me the price and I paid her the $148.50. A few weeks goes by, i haven't heard anything, after a month they called me to come in for a second fitting. When I got there they basically told me that the first lady I spoke to shouldn't have taken on the job and that they couldn't do what I asked. However, they had altered the shorts and tried to do it, but to no avail. So now I have a brand new pair of shorts that has been cut up and altered, but not in the way we discussed. I wanted them to give me the money for the shorts and a refund, but they said no, so I agreed to just a refund and they would return the shorts. They then send me an email with a document attached that is essentially an NDA and say I have to sign it to get the refund and the shorts back. I am not signing an NDA, so... I went online and posted a review stating exactly what I have said here, and then they emailed me to take it down. I am not taking it down. They are hold both my money and shorts hostage until I do so... I tried to fight the charge via my credit card company, but they lied to **** and showed them the receipt as proof. Well they ask for payment upfront, so of course there's a receipt, but there were no services rendered. Please help! Attached is all of the emails that will verify my story.
