I had a XXXX in XXXX XXXX and was transported to the hospital by ambulance. I had medical insurance at the time but I did not have my insurance card at the time. Later, I called and provided my insurance information but the amount on the bill never changed. I called again but they insisted that I still owed the same amount regardless of insurance. After my refusal to pay, due to the refusal to apply my insurance, they sent my account to a debt collector. This was about 5 years ago and Apex ( debt collector ) has continuously called, at all hours of the day yet they never leave a message nor have I ever received a paper bill. This debt is negatively affected my credit report.
