Holyyyy!! This happened To me as well, I seriously considered leaving tmobile.Be careful trading in with T-Mobile. I send them my 11 Pro Max to get my 12 Pro Max 2 years ago and they tried the old "we didn't get it bs" about 2 months after I sent it in and tried to get me to pay full price. They gave me the runaround for about 4 weeks until they finally located it. I don't trust the independent company they use and will never do the mail in trade in again with anymore.
There are plenty of horror stories out there about this so just be careful. BTW I'm just gonna buy it directly from Apple and then sell mine probably on Craigslist if I can't get a friend to buy it.
They took my promo away from me because they couldn’t locate it, mind you I shipped it in their box and used their label.
I ordered my phone in November 2020, they didn’t locate the phone until Jan 2022! They hit me up this year and said it was located. Here’s the catch…bc it was beat up on its journey to them they had to lower how much credit they were giving me. I tried to fight it but they wouldn’t budge smh
