Walmart Family Mobile Being Billed for a PRE-PAID PHONE for 2 months, that was off since December. Albuquerque New Mexico

I received a bill from Family Mobile for 79.98 dated March 9 2015. I called to enquire why I was receiving a bill, was told to go to the store to have them verify who I am because I could not remember my pin. I went to the wireless center today, was told I need to call 877-7608760.

I spoke to a Gaby who informed me to now write to T-Mobile because they cannot do anything for me by phone. I am upset because this phone was broken on December 24 2014. I replace it and went with a different prepaid service because t-mobile service was the worse.

I still had days left on t-mobile plan when this happen.  I was told that I was supposed to call them and let them know I was ending the service with T-Mobile. This makes no sense to me especially when it was a pre paid phone; I mentioned this to an agent on the phone and was told it's a post paid phone.

I said I don't have a contract and that I am not obligated to pay that 79.98 and to that was told you have a contract and you don’t have a contract. I either have a contracted or don't. It can’t be both. More confuse now than before. One thing I am not confused about is that I will not be paying a bill for my "post paid cell phone" that has been off since December 24/2014.
