Commerce Payment Systems over charges to my business checking account Hewlett, New York

Commerce Payment Systems  over charges to my bussiness checking account Hewlett, New York  

I signed up with Commerce Payment Systems for a merchant credit card processing account.  The monthly charge to my checking account started at the $4.95, I was told it would be.  Along with a $49.00 yearly charge for the termial.  After about 6 months the charge increased to $13.37 and then a few months later to the final 4 months of $161.32, $61.85, $110.85, $61.85. 

When I got the $161.32 charge I called and was, told it was a Master Card and Visa charge.  The next month the $61.85,  I assumed was the yearly charge and the monthly charge, so I did not called.  Then the $110.85 came, I called and was told I have a minimun charge of  $35.00 but the representative did not have any other answers to the higher charge.  I asked to speak to a supervisor, he said one would call back.  They have never called, nor have answered any other phone calls or e-mails.

The final $61.85 I got stuck with before I closed my checking account and sent the therminal  back.  I feel this company  is dishonest.  My recomendation is don't deal with them.
