I have made payment in Full to the collection agency ( Receivable Performance Management-RPM, Washington State ) since XXXX 2014 and after several calls to the Debt collector, the information still remain on my credit report as the OPEN unpaid. i have called them several times in XXXX, XXXX, XXXX, XXXX and now XXXX to correct this error and they promised to remove but have not done anything. This inaction is affecting my credit despite making full payment.
