T-Mobile Bait and Switch scam on December 2021 "Free" upgrade to IPhone13 + airpods

Same thing here.  Traded 3 phones.  2 were Sprint Leases (apparently I was to receive credit for them).  One was owned outright.  They gave me credit for the 2 Sprint Leases, but they deleted my promotion on the non leased phone after 2 billing periods claiming the phone was not traded in.  Then they acknowledged it was lost but told me they need to investigate it before re-enrolling me?  Why am I accountable when they lost the phone?

When I received my 3 new iphones via mail, I called and asked for instructions on returning my handsets for the promotion.  They said - "it's simple - just take it down to a local Tmobile Store".  I figured that is great.  Frankly - I suspect they use this as a way to claim a customer never turned in a device.  That's awful and unethical.  Maybe their store associate pocketed it.  Who knows.  That is on them for having a poor system for accountability.  I suppose I should only handle things through services that are traceable like Fedex from now on.

If anyone finds a lawyer willing to take on this unethical behavior, I’m happy to enjoin a class action suit if there is a benefit.
