SKS Associates ripped off my bank account for $114.23 without notifying me. New York, New York

I checked my account on 4/2/11 and found that SKS Associates had taken $114.23 out of my account on 3/30/11.  I never received any notice and did not recognize this company so I phoned my bank immediately and they told me to call the company and see if I had ordered anything.  I told them that I had never contacted this company and demanded to file a claim against them and asked if there were anything I could do to prevent them from taking anything more from my account.  They were very reluctant to file a report but I insisted and they complied.  They said it would take up to 10 days to investigate my claim and there was nothing they could do to prevent them from taking further funds from my account.  I leased a machine from Northern Leasing in 1996 and paid it in full years ago.  I checked on line and saw that this scam has been pulled on several people in the last few days.  If anyone is filing a class action suit against them, I'm in.
