Accounts Balance Issues

Honestly, not sure if Edgars is robbing me or if their systems are messed up. For the past 3 months i have tried to resolve an ongoing issue regarding my account and how, even though i am paying more than the monthly installment, my account always seems to be reflecting negatively. I was informed that my account went into an overspend(Even though i had more than enough funds) that's why it was in a negative, then i inquire about it and get told that it hasn't been reflecting negatively, however, even though i seem to be making constant payments, it always seems to reflect negatively. I have made numerous calls, been on hold for 30 minutes and then they hang up. I am so frustrated with constantly having to call in and still not receive any assistance.
