Aramark Uniform Services Did not fulfill contract we cancelled they keep billing us refusing cancelation Portage Nationwide

We entered into an agreement with an individual that is no longer with their company. That individual stated multiple time that we could cancel the service at any time without penalty. When we tried to do that, we were informed that we would be in breach of contact and would charged cancelation fees and penalties, but they said it appeared that we were being over charged and they reduced our bill by almost 50% if we did not cancel. We took their offer to avoid the fees but not only was the bill reduced by @ 50%, so was the service. The driver repeatedly showed up with out our rugs or logoed mat. I had my attorney review the contract and he informed me that now Aramark is in breach of contract by not being able to fulfill their end of the agreement and thus we had the right to terminate the contract. We send a certified letter to Aramark at the beginning of July 2014 which Brett Sabol from their South Bend Office responded to immediately. He responded with saying that they did not believe that they were in breach of contract but he would run it up the ladder and get back to me. Its now Sept 2014 and we have heard nothing from Brett but their driver showed up here today demanding back payment. These people are trying to extort money from us after not fulfilling the obligations they agreed to in the contract.
