First Federal Credit Control Debt Collection Complaint

First Federal Credit Control Debt collection department,

Medical False statements or representation Attempted to collect wrong amount North Carolina

- - reported to the credit bureaus that I had an unpaid balance of $290.00. The balance should have been covered with by my health insurance company. I ended up switching jobs during the billing cycle, but I maintained health insurance the entire time. Nonetheless, I called them and the error was corrected and they said that I did not owe any money. They said they will have it removed from my credit reports. About 2 weeks later, I get a call stating my insurance did not cover it all and that left a balance of $57.00, I said okay, Remove the old amount of $290.00 and I will pay the $57.00 once it had been removed..A week or so after I spoke with them about the $57.00, It reported to my credit reports. So now i have - collections on my credit report and it dropped my score significantly. I am in the process of trying to buy a home and this is conflicting with my pre approval from the bank. THey told me at - - that it should only take about two weeks to have it removed from my credit reports, but I have yet to see that happen.
