SKS Associates took $104.72 out of my bank account on 3/31/11 New York, New York

SKS Associates took $104.72 out of my bank account on 3/31.
Suupposedly this was to cover a shortage from a Northern Leasing account they took over.
However, I have not had an account with Northern Leasing for YEARS!!!
I paid my lease off to Northern Leasing as agreed in my terms with Northern Leasing.
That SKS was able to access and take money from my account without any notification to me is not only unethical, but illegal.
I never had an account with SKS Associates and had cleared my lease completely
and finally with with Northern Leasing.
