HAHAH! About 5 years ago.. I got a letter from these idiots"Cavalry". The letter said I owed money from a Sprint account that was never paid and that they have been giving my info so they can collect. I told them that I have Sprint for one 1 a while back but everything was paid on time and never had a problem so it was puzzling why I have a credit owe issue. So anyways. I said"You need to fax, mail or do anything to show me a Sprint letter bill stating that I owed this money. The lady said.."Sorry but we do not have any bill or recite for this. I said.. "OK. bye bye." And hanged up. I never heard from them again. It was a scam. SO it looks sprint has a lot of leaks.
