So on launch day I received my mom's iPhone 7 32GB which replaced her iPhone 6 16GB and when I ordered the phone I told the agent (after he asked first) that I'd be trading in the iPhone 6 as part of the promotion they're running. He noted it and everything was fine but he didn't give me any type of RMA number for the trade in. Well, when I got the new phone on 9/16 I called T-Mo and the rep said all I'd have to do is return the iPhone 6 to T-Mobile and they'd take it from there, and he sent me a UPS prepaid return label. The return label DID have the iPhone 7's order number at the bottom which helped me feel better about it but I still had no papers from them or anything to put in the box. They've had it a week today and I haven't heard a single thing from them yet. I chatted with T-Mo on Friday and the guy said I should be fine and he verified that they received it but that no promotion was applied to my account, and that I (well, my mom actually) should receive a text confirming receipt of the trade in. Just wondering how this has gone for everyone else because I'm starting to get a little worried. They've had the old phone for a week now so I would've thought they'd have said something about it by now. I did search first before posting so please excuse me if I missed any posts or threads. Thank you guys in advance for any help.
