SKS ASSOCIATES Unauthorized DEBIT of checking account for TAXES,FILING COSTS,LEASE AGREEMENT terminated 04/2006 New York, New York

I received a letter on March 12, 2011, stating that SKS was debiting my checking account on 3/11/2011 - unless I wanted to pay by another payment method and to contact them Monday thru Friday - (amazing that I received the letter on Saturday - the day AFTER they debited my account)
When I called them and told them I did not owe this money and I wanted to see the "audit" that stated I did -  they told me I had to prove that I didn't owe it.  I asked to speak to a supervisor and was told one would call me back - yeah, right!!  I'm waiting on that!!  I have contacted the Attorney General in my State (Missouri) and also left a message on 1-800-886-0320 - which is a number of an attorney representing a CLASS ACTION suit that has been filed against Northern Leasing.  I urge everyone that has this problem to also call this 1-800 number!  Let's get the con men in charge of this scheme!!
