I VISITED WITH MY XXXX DOCTOR A YEAR AGO, XX/XX/XXXX. AT THIS TIME, I WAS NOT INSURE. I SELF PAY FOR THE XXXX VISIT. UNFORTUNATELY, I WILL BILLED XXXX DOLLARS. I WAS ERR FOR NOR FOLLOWING-UP WITH XXXX XXXX TO INQUIRE ABOUT THE DEBT..HOWEVER, NOT LONG, I RECEIVED A LETTER FROM QAR RECOVERY ABOUT THIS DEBT. I GOT FURIOUS NOW AND CALL XXXX XXXX BILLING OFFICE. I SPOKE WITH A REPRESENTATIVE AND INFORM THEM THAT I SELF PAY FOR THE VISIT AND IT IS THE POLICY OF XXXX XXXX TO REDUCE THE PRICE WHEN THE PATIENT IS SELF-PAYING. THE REPRESENTATIVE AGREES AND APOLOGIZE AND THEN REMOVED THE OUTSTANDING BALANCE FROM MY ACCOUNT. I ALSO CALL QAR AND EXPLAINED TO THEM THE ISSUE AND THEY INFORMED ME THAT THEY WILL LOOK INTO IT. THIS ISSUE HAS BEEN RESOLVE FOR OVER A YEAR NOW. LAST WEEK, I RECEIVED A NOTICE ABOUT A CHANGE IN MY CREDIT HISTORY FROM MY CREDIT PROVIDED. WHEN I CHECKED, IT WAS XXXX.I TAKE MY CREDIT VERY SERIOUSLY AND I AM VERY CONCERN AS TO WHY THEY HAVE PUT THIS ON MY ACCOUNT.
