Incorrect billing for months

Worst ever! I've wanted to settle my account for months as they kept over charging me, no ffeedbad, the case went on for months and I kept on getting penalized as they want to deduct the wrong amount of money from my account. This is still not settled even though I've paid my account and they just don't give a damn how badly it's affecting my credit score for not updating my account. Would not recommend this service to anyone. They're useless!
