I received a letter from Commonwealth Financial Systems stating that I owed money to : XXXX XXXX XXXX Services in the amount of XXXX. The letter stated that they had purchased the account and if I considered the debt valid they requested payment. They further stated that if I failed to let them know in 30 days that I disputed the validity of the debt they would consider the debt valid. They also called to request payment and asked for last XXXX digits of my SSN. I told them I do not give out information on the phone. They have a spot on the letter for you to fill out your credit card information and offer XXXX automated payment. They push hard for payment and are hoping you just pay it right away without taking the time to research it. Obviously, XXXX XXXX XXXX is not a real company and the debt was not owed but they sure make you feel like it is.
