SKS Associates stole from my bank account, as well. New York, New York

Earlier last week, I received this delightful letter from SKS Associates. The statement was that they had taken over Northern Leasing and decided that I owed more money. 

Without giving me a chance to speak to them, they went in and snagged it from my account ($77.82). This has me worried. SKS could be like another 'Bank of America' and decide every few months, that people owe them for whatever made up reason and just take more and more money. 

Also, my contract with Northern leasing has been closed for years. I was told that i was all paid up. If my contract was followed 100%, then I shouldn't be worried and/or victimized by such robberies.
