Tmobile trade in is SCAM

Be an advocate for yourself and tell the customer service rep you believe you're being scammed and that they do have your phone. I had the same issue except I was receiving the trade in credit for two months and then it went away. I did a lot of research and found people having similar issues so I called customer service and basically demanded that they adjust my bill to reflect the trade in credit and the representative ended up adjusting my bill. She also told me that they believe there was damage with my iPhone and someone was going to call me back within the next month to tell me what happened (side note: I had already heard from a store rep that the warehouse was saying they never received my trade in decide). Five hours later I got a call at 8:30pm with a representative from the warehouse investigation team saying my device was nowhere to be found and that they couldn't do anything. She proceeded to say the only solution was to file a claim with UPS. Luckily, I had already looked into filing a claim with UPS but UPS doesn't allow you to file a claim after 60 days (this is now 70+ days after my device was delivered). I responded to the customer service agent very sternly telling her the info about a UPS claim and that I'm now stuck in this position where nothing can be done. I continued on to say that I believed T-Mobile has my device and they're lying to me and scamming not only me but many other people. I told her I found this page and many other posts about people running into the same problem. The minute I mentioned scam she "conveniently" found my phone.
 

MY ADVICE: if you have proof from UPS of delivery and it's a couple months later, be an advocate for yourself. Tell them you believe you're being scammed and that they have your phone. I'd be curious to know how many people will all of a sudden get an answer that their phone has been found when they mention this information.
