I noticed that my credit score had dropped precipitously from XXXX to XXXX due to a negative report. When I ran my credit report I found a false report had been made. PMAB LLC is a collection agency employed by XXXX XXXX XXXX. PMAB LLC reported an account balance of {$440.00} as not paid to the XXXX and other credit bureaus. PMAB LLC had good reason to know the account was not mine. When I telephoned PMAB they admitted the charge had been made by my XXXX year old son, not by me. They identified my address as a former address where I have not lived for 8 years. When I complained I was told I should get my son to pay the bill. I am not responsible for the bill. I am not responsible for getting my son to pay his bills. When I telephoned XXXX XXXX XXXX to complain, they told me they had no balance due on any account from me. That leads me to believe the collection agency is an unscrupulous agency which preys on the elderly by engaging in extortion. Please assist me in regaining my rightful credit score by the elimination of this unlawful report. I have attached a copy of the PMAB item as shown on my credit report.
