"Beware of T-Mobile's phone payoff and porting promotions. Five months ago, I switched to T-Mobile under an explicit agreement that they would pay off my existing device balances with AT&T and port my numbers. I provided all balance info, but T-Mobile failed to coordinate the release with AT&T.
As a result, my numbers were never ported and my phones were never unlocked. For 5 months, I've been paying AT&T to keep my active service while T-Mobile has continuously billed me $281.84/month for completely non-functional lines--totalling $1,409.20 in unearned charges. After endless dropped calls, hours on hold, and broken promises of call-backs, their only solution was for me to pay off the phones out-of-pocket for a 'possible' reimbursement or cancel and owe $1,000+ in device fees. A formal demand letter and FCC/FTC complaints have been filed." read more
