SKS Associates Unauthorized withdrawal of funds for equipment lease that ended in 2005 New York, New York

This company withdrew $132.25 from my checking account today.  After some investigation, I found their telephone number and called them.
I was told they took over for Northern Leasing and was collecting a tax that was not collected when I leased a credit card machine. The lease ended in 2005 and the machine was returned to them.  After six (6) years they came after this money.
The lady on the phone said I was notified of this transaction, however, I was not.  They are very nasty and insists the money is theirs.
