T - Mobile TMobile Rips off Customers! Internet

TMobile has not renewed romaing agreements with AT&T to use their towers.  Therefore I now get 1 bar of service, 2 bars on a good day and tons of dropped calls.  I've tried to talk to them (still working on it) to let me out of the contract without penalty and they claim they are providing all the services they need to be.  They check your SIM cards, your phones, claim to send engineers our to their towers to "check for obstruction", you name it, they tell you anything to keep you hanging on.  They had me try new SIM cards in my phone telling me it would give me more bars and now I get no service.  Locked up my phone.  I cannot get to names or contacats.  They had me try it in my sons phone to check the card, now his phone no longer works either.  I am waiting for a service tech  to call me this week to give me the engineers report and activate the new SIM cards but after reading all of the nightmares online, I'm not very confident I will get a resolution.  Something has got to be done about this company.  Taking people's money and are not providing the service the contract states; the one we signed on to.
