I had sent my old device iPhone 6 Plus to Tmobile for a trade in credit. The tracking # showed Tmobile warehouse already received it but no credit was issued. I have been contacted customer service so many times and they said they didn't receive the

I am in the same boat.  I traded in an iPhone 6.  Was noted as “received” on the UPS tracking site.  I followed the same steps, printed the shipping label as directed.  Still no acknowledgement from T-Mobile that the phone was received.  Very shady business practices.

I just encountered some trade in scams. They encouraged me to get a new iPhone X and trade in my iPhone 6, saying it is qualified. Little that you know they declined the deal saying there is liquid damage, thus the trade-in is not qualified. I was never informed of procedure to check first if there is liquid damage, I am the original owner and I know the phone was never in any liquid. But since I didn't check, they can say whatever they want to say just to deny trade-in credit.

I asked to send my phone back and I am willing to send them the iPhone X, guess what, they allow me sending the iPhone X back but no return of my iPhone 6.

This is a scam. This is using a tactics to get you to buy a phone, since the deal also include auto debit, the consumer has only one choice to keep the paying the phone.

Don't do the trade-in, especially with T-mobile. I will file a complain to FTC. I will write to my congress and I will bring it to Department of Justice's attention.  There is a history with T-mobile, they can't just quit scamming and cramming. In 2014, T-Mobile lost a case filed by FTC and resulted in paying at least $90 million to settle a Federal Trade Commission lawsuit of cramming consumers.

The same thing happened to me.  I have receipt of them receiving my device; also, phone calls from a few different t-mobile reps. that the they received it; however, can not find it....... Won't give me credit for it; while at the same time raised my bill, tremendously (I was suckered into all the gimmicks) to get all the discounts!!!!  If this happens,-- this much, isn't there something we can do!!!!

I have kind of similar problem. I bought a Amazon certified phone and send it to T-mobile warehouse Texas for trade in program and I got an email saying they got the phone however they didn’t give me any credit. When I asked they said find my iphone is still turned on that is why I didn’t get credit, which is 100% not true. Amazon never sell phone without resetting and I also checked everything before I sent the device. Amazon also sent me the proof that find my iphone is turned off on that device, and they said there is also a website to check with device imei number to see if find my is turn on or off. They did Handset… research form, but when I read the problems of other people now I have no positive hope. Based on the conversation here, looks like they used new strategy to scam people.
