Leaders merchant services Deceptive fees, unAuthorized fees Thousand Oaks California

I am a small business and was looking for a fairly cheap credit card processing company to handle the few credit cards I have a month. I was told the 3 different credit card fees, the no monthly payments and the maximum fees they would charge for a credit card.  The lied on every account  . There are authorization fees, license fees, nabu fees, kilobyte fees, acqr fees, dues, fixed network fees, monthly fees and a PCI compliance fee... I was told that none of the credit cards beng used fit into he category of the original claim. In fact no credit cards for their original quote   A $2500 credit card transaction cost me $186. 45 in fees. I was also told it was a 1 years contract with no cancelation fees.  Now I find out it's 3 years with a $400 a year cancelation fee.  My bank had even earned me about the company taking unusual amounts of money form me.. I also get charged a fee if I don't have any credit card transactions . I feel I have been scammed and from the reviews I read, it seems I am not alone.. I would like to finf out what I can do to part ways with this sham of a company
