Phone Buy Back

I talked with your representative he told me that they would pay off my phone from another carrier

and after i made the switch and tried to send them my payoff now they tell that my carrier is not on 

the list that they say they will payoff. I was never told about this list and even there addvertisements

does not mention it. This is just one of the other lies that there representative told me. Its sad that they

think so little of the customer that there money hungry greed comes before the customer.
