I have not been able to contact anyone by phone or website. The website will not accept the account number. There is a voicemail in which no one calls you back or answers. I have made 2 payments, but can't confirm the second one has been received. It took a month to get the first payment posted. I will not be sending another payment to this fraudulent company. Why would UNC ER doctors use this type of company. This terrible company needs to be investigated and shut down.
