ARS ( Account Resolution Services ) is claiming they received a debt from XXXX XXXX XXXX which oversees ER doctors. They claim that XXXX has record of me seeing a XXXX XXXX XXXX at the ER of XXXX XXXX XXXX in XXXX, VA in XX/XX/XXXX. I did not visit the ER at XXXX XXXX XXXX at anytime in XX/XX/XXXX. I never saw a XXXX XXXX. I called XXXX and was routed to an organization called XXXX. I spoke with a representative who tried to look up my collections account by all means possible ( i.e. First name, Middle name, Last name, SSN, birthdate, etc. ) with no success. They said that I was never a patient with them. Being that I did not use the services of the ER and that there is no record with the original debtor I am contesting this debt. Lastly, I was never notified of this debt with any statements or phone calls. The address they claimed to send the statement to that came back as " undeliverable mail '' was not an address I was living at the time they claim the services were rendered. The debt appeared on my credit report in XX/XX/XXXX, two years after the supposed event. I was made aware of the debt when my mortgage loan officer sent me a credit report recently. It was not on my credit in XXXX. I have filed a dispute with all XXXX credit bureaus but wanted to make you aware that this is not my debt and I was never notified before it was negatively reported on my credit.
