Oxford Management Check Fraud Melville New York

I owed a bill and these people called me to pay that bill. I paid that bill in full with them over the phone approval to draw the money out of my checking account.
Ten days later they withdrew another amount out of my checking account. Went to my bank disputed the funds and was told that the name it was being drawn on was Roy Cheatham. One month later and again a different amount was taken out and charged to Cheatham. The bank can not keep them from drawing out unless it is the same amount every month.
I have called Oxford and they can't tell me anymore other than I do not own them anything. They can't tell me anything about Roy Cheatham because of privacy issues.
If they try to draw money on me again next month they are all out of luck.
Account closed.
Please be aware if you pay them with checking account they may try this with you.
