Comcast Comcast Business Class Delay in turning off service Philadelphia, Pennsylvania

I wanted to cancel my comcast business service for over a year but comcast automatically renewed the service.  I waited the year and called one month ago and they said I still had a month left on the contract.  I called today and they said the contract was up but I had to give them 60 days notice. No one ever told me this when I called previously.  I had to sign a request to stop the service but the date is for two months from today, 5/5/2013. This is a small family business, I don't need the service, and my husband, who operated the business, passed away almost 3 years ago.  I believe I am being treated unfairly.  The business name is Barrington Software Inc.  and the address is  831 S Grove Av, Barrington, IL.  The comcast account number is:  877110101013**** Thank-you,  Roma K
