Commonwealth is trying to collect a debt from me for XXXX XXXX XXXX XXXX. I contacted original creditor in 2014 and they sent a letter to Commonwealth that the debt did not belong to my SS # and to remove all debt from my acct. Commonwealth did so. However one year later they put the debt back on my account. I called them and told them it was a mistake, they agreed it was and told me to dispute it. I have disputed it but it keeps coming back on my credit reports.
