NHRMC sent a bill to this collection agency even though payment arrangements had been made and I was paying on the bill. Jon Barry and Associates is located in Concord NC. I have tried for months to remedy the situation and explained that this debt has been paid. They are now ignoring me, despite sending correspondence via certified mail with return receipt. I have sent them proof of payment multiple times, and that the account has been paid in full since 8-07. Yet it is still being reported on my credit as unpaid. Who do I contact next to complain about this other than the Better Business Bureau?
