I was a XXXX customer for a couple months and i agreed on an amount on a 2 year contract and that was XXXX dollars a month everytime i got my bill it was higher than the agreed on amount so i just kept paying my XXXX dollars and then late fees happened so i canceled the contract because they broke the contract agreement and submitted my account to multiple debt collectors and now its with XXXX that was already removed from my credit report.
