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

I've gotten scammed for the 2nd time now - shame on me!!!  The first time was in November of 2020 when we were told the new phone we were upgrading to was on a free promotion.  We continued to be billed and kept being told after 2 billing cycles, you will see credits each month.  NEVER HAPPENED!!!!  Trying to reach anyone who will help in impossible.  Nothing but a run around.  Then, in December 2021, we also fell for the FREE IPHONE 13.  Both of my daughters traded in their perfectly good phones (one of which we actually paid $150 to fix the screen so we could trade in).  I am now being charged for one of the phones and I continue to be told this was a buy one get one deal.  Why in the HELL would I do a BOGO deal when they had a free promotion for the phone!!??!!  I am now going through the same hassle as before.  They have you sign so many papers and sit in their building for so long (we were there a total of more than 6 hours over two days!) that you don't know what is going on.  Despite the repeated assurances that "both phones are completely free - I promise" we are once again paying for what was supposed to be a free phone.  I WOULD LOVE FOR SOMEONE WHO CAN ACTUALLY HELP FROM TMOBILE TO CONTACT ME AND FIX THIS.
