On XX/XX/XXXX, I was contacted by a collection agency called, Advantage Group, XXXX, in XXXX, New Mexico. The call was in regards to what they said was XXXX outstanding debts. The first debt was from XXXX XXXX ( XXXX, NM ) for {$49.00}, for date of service on XX/XX/XXXX.The second debt was from XXXX XXXX ( XXXX, NM ) for {$45.00}, for date of service XX/XX/XXXX. I was not given any type of claim or reference number for these accounts from this collection agency. After a brief conversation with a woman at this collection agency I called my insurance company, XXXX XXXX, and the XXXX XXXX XXXX Department. After further investigation, XXXX informed me that the bill in question to XXXX XXXX was paid in full on XX/XX/XXXX, Claim # XXXX. XXXX XXXX XXXX stated my account had a zero balance and the debt had been paid on XX/XX/XXXX in the amount of {$45.00} on Acct # XXXX. I am not sure if this Advantage Group is legitimate or not, however, they certainly are living up to their name of taking advantage of unsuspecting people. I live off XXXX and a small government pension. I am appalled that this or any other company of this nature preys upon people. If it has happened to me how many others has it happened to. In spite of my health conditions, I understand how insurance works as I am retired from XXXX after nearly 40 years, of which over XXXX was served as a XXXX at the XXXX, NM XXXX XXXX XXXX. This fraud must be investigated so that others, especially the elderly, will not be taken advantage of by this or any other company of this sort in the future.
