Be Careful when returning defective gateway routers

Same thing is happening to me!  My gateway was in PRISTINE condition when returned, and I'm now being charged for a "damage fee."  The customer service representative I spoke with last night could not help me at all because I never set up a 6-digit PIN. Now I have to go to a store for them to "verify" my account for THEM to then call customer service to speak with me.  T-Mobile is a joke.  It's fraud, plain and simple.  We no longer want / need their service, and they're sticking it to us with bogus charges.  I loved the internet, but recently moved and T-Mobile internet was not available at my new address.  I will never be a T-Mobile customer again. Who thinks of taking photos of the device before sending it back?  Well, definitely do!  At least you may have a leg to stand on, although they will probably charge you anyway.
