Sprint PCS rip off and unethical practices.

About a year and a half ago, my husband and I purchased a Sprint PCS phone from Radio Shack. We paid a $100.00 deposit for this phone. We told them to make sure the number was local for the Vancouver,WA area. We got home after the phone had been programmed and I tried to call the cell phone from the house phone and found out it was long distance. My husband called Sprint and he was told that the number couldnt be fixed until the next service period a month away. It took 4 hours, but we got it fixed. He had a $400.00 limit on his usage per month. Everything went fine until he got his phone deposit back after the 1 year contract. For some reason, his limit was set back to $125.00. We would pay the bill and a week later, the service would be shut off. Come to find out, they were charging the monthly service fee of $75.00 before the service period was up. That left my husband with only $50.00 on his monthly limit(of which we knew nothing about in the first place.) My husband is a long haul trucker, so I need to be able to get ahold of him. After 3 months of this nonsense, we finally shut the service off and went and got a different service. Do we still owe them money? Yes. Will they get it? In my own sweet time.
