Warranty exchange fee

I have a Moto Stylist that malfunctioned from none damage (dropped; water damage etc.) T Mobile online tech went through a series of test-plus took phone to Howe Ave store, Akron Ohio. Talking to an online agent I was assured the phone was under warranty inwhich I was told also that I may be charged between $5 to $20 for a warranty fee! Guess what?…..Naw don,t! When my replacement phone arrived  and I went to the store to pick it up I was charged the $20 plus tax which was necessary to be paid before I could get the replacement. To be fair T-Mobile gave me a credit for $20 off my bill. The old phone I hade accessories…..liquid glass screen protection for one (Which when I inquired they were out of stock. ) I synced my phones but the malfunction erased a lot of information and all but one picture. I had talked to a tech that fixes such issues for a price but was told having the old device could help. (This was relayed but I was told the flawed device must be kept by the store.) When I asked about the cost of my accessories and the price it would cost to pay a non T Mobile tech to attempt tp retrieve my lost information I was told by an in-store agent that the lost information from the defective device could not be retrieved as it did not come back when I synced my device: as for any other loss I must contact the maker of the phone and deal with them regardless that I purchased the phone directly from T Mobile. T Mobile has no corporate office contact for customers and when asking for a supervisor or a complaint department a runaround situation begins. (More of concern...I have two phones under the same plan- I had to take the paid insurance off one of the phones to lower my expenses...guess which phone malfunctioned!?…..You got it!…….the one with no insurance.)  A lot of individuals under 50 may not remember good customer service and/or customer compensation when damage is not fault of the customer.) I am stuck with another year of a two year contract with T-Mobile without having to pay for early termination fees or the cost of both phones which undoubtfully if not paid for T Mobile will turn over to collection.
