SKS Associates Company took $68.20 out of my bank account from a lease that ended in 2007 (3/11/2011) New York, New York

I had a lease for a credit card machine with Lease Finance Group, LLC (LFG) from September 2003 through August 2007. 

A letter dated 2/28/2011 stated that I owed SKS (who purchased LFG recently) back taxes on the lease and that they were taking $68.20 from my account.  The letter was sent to the business location address.  I do not give out that address, and only check the mail once every month.  By the time I found the letter, the money was already taken from my account.  My bank tells me that they can not get the funds back and I need to dispute this with SKS.

I have written a letter to SKS, but since they have the money I do not expect to hear back from them.

This company seems to be a bottom-feeder to me.  I do not beleive that I owe them any money.  I believe they are taking money knowing that small companies do not have the time or resources to sue them.
