Electronic Payment Systems EPS will not let you out of your contract Internet

I was pressured into using this company by a sales person.  Do not sign up with this company.  They will not let you out of your contract and continue to bill you after cancellation.  After recieving my cancellation letter, the company told me that they were raising my montly fee for the remainer of my contract by $10 a month becase I was on a "discounted" rate.  They told me that they are going to continue to charge me the $35 increased monthly fee for 11 months.  The service people were rude to me and continually hung up the phone as I tried to make since of the increased charges.
