Contacted by Jeff Morgan from USA cash network. He said I owe $ from a cash advance from 2011.
I went to the bank to check deposits for the entire month and there was no deposit of the amount Jeff said was made. The account was closed before the date Jeff indicated. Called Jeff back to tell him of my findings and he said that i did not want to clear this matter and that he needed my supervisors name and the person who writes my check so that he can start garnishment. He said I should pay the resolution amount in two payments and the first payment was due in24 hours via moneygram western union or through Walmart. Told him I did not have the $ and again he asked for my supervisors name and phone number to start garnishment of my check. I receive 6 missed calls from his number. Help.
