I, too, was a victim of this scam. Northern Leasing Systems, Inc. (now doing business as "SKS Associates") simply yoinked $195.00 from my bank account on March 2nd, 2011. I had terminated my credit card processing service with them in April, 2010 for similar unauthorized debits. They are notorious for victimizing small businesses with their bad faith contracts and outrageous fees for handling credit card transactions.
In my case the bank account had a near zero balance and had been relatively dormant for some time, so the debit triggered NSF charges and other fees.
It took filing a dispute with the bank to figure out that SKS Associates was indeed Northern Leasing. I ended up getting on the phone with a bank exec and we called them. Talked to a man who goes by the name Paul (no last name). He claimed that they sent a letter notifying me of the charges back in February, 2011. I asked him to send me a copy of the letter. It turned out that the delivery address was incorrect. The letter claims that my company owes $195 for (unspecified) "tax processing and filing fees" and indicates that the bank account will be debited on March 2nd.
Paul refused to clarify what specific tax and processing fees were owed, and also refused to fax supporting documentation for the debit (other than the letter). When the bank asked for the same information he stated, "Well, we've already got the money so I don't need to do anything of the sort."
I have requested the bank to close the account and informed them that I do not intend to refund the charges without further documentation. I don't think this matter is over. I'm amazed how Northern Leasing can continue processing charges with impunity like this against so many unsuspecting businesses. Is there a way to stop them!!??
