Used XXXX Services XXXX, live XXXX. I have XXXX XXXX insurance. Used XXXX for Emergency. XXXX XXXX mailed billing information to an old address not used. I provided at time of service my current address. Collection agency said they could not collect from XXXX residence as they are not licensed XXXX. Paid the bill, and have repeatedly asked for the the entire file showing mailing dates with responses so I can recoup my {$460.00} from XXXX for the service. No Response from King Credit, XXXX. Frustrated with their lack of concern.
