I have two trade-ins, one phone, I did not receive a return label with the new phone and I was unable to obtain a return shipping label. At 1st, I was given the wrong info on how to get a replacement return label (once I figured it out, I had already sent it off). So I sent both returns in the same box. I did attach a note to the phone with no label but not with the submission ID which I just learned identifies the returning phone. How can I be positive that my phone will be processed properly and receive my trade-in credit?
