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

I restarted a contract with them after being promised a promotion buy 2 get 1 phone free and 2 pairs of old 2nd gen air pods for free. I gave them my mint condition IPhone 12 as trade in and got scammed! I'm stuck with old generation air pods which I'm having to pay 10.47 monthly for each for 12 months!! And the "free iPhone" they are taking off 27.50 Per month x24 months  which is 660 but I'm being charged 800.16 for phone?? This is terrrible ! I've been with T-Mobile for 8 yrs had issues with them here and there but nothing like this! I can't believe there is a thread and number of cases like mine.. headed to the store to see if manager can help, She's the one who sold me this deal… Tampa customer service rep Leney and her manage Calvin are a joke.. I was placed on hold as she ate her breakfast (forgot to press hold button I guess) then she realized and said hello? Sorry my manager said nothing he can do.. seriously?? Waist of 39

mins of my time!  livid at this point.
