I have a medical bill on my credit report. I carried state insurance at the time of the services. I contacted the doctors office and it was to be taken care of. Now its listed on my credit report. I called the debt collector and explained the situation and asked that it be disputed. She refused to dispute it and hung up on me. The creditor information isCredit Management Company ( XXXX ) XXXX am dumbfounded to be treated so rude and I am upset that my rights were refused.
