T-mobile Scam

We switched from Verizon to T-Mobile on October 4, 2023 in Richmond, Indiana. The store did not have the iPhone that we wanted in stock. T-Mobile shipped the phone to my house and requested I ship my phone to their facility. I printed the tracking number that was provided by T-mobile and shipped my old phone to the facility. The tracking number indicates that the phone was received by their facility. T-Mobile has failed to credit my account thus voiding the promotion we signed up under and charging us over $800. I have tried to connect with Tmobile numerous times over the phone and in the store and no solution has ever been provided. T-Mobile fails to provide anything in writing indicating they will honor the promotion we signed up under and still showing an outstanding balance.  This is a scam and I would like to hold T-Mobile accountable for their shady actions.
