DTE Energy Home Protection Plan Protection or Conviction??? Detroit Internet

I signed up with the DTE Energy Home Appliance Protection plan in February of 2015. The "friendly" representative recruiting new accounts came to my door, explained the program benefits, costs, and assured me that I could cancel at any time!  Well that was a lie. I had a service to my air conditioning until in June of 2015, so when I called to cancel in October I was told I had to continue to pay for the program for the full benefit year (February 2016) or I would be charged for the full cost of the service I received.  When I tried today (january 29, 2016) to call and cancel the service I was told that my request would be forwarded to the "cancellations" department and someone would call me back after reviewing my account in 10-14 days!! This is ridiculous.  These people will not let you out of the paying for this program though there was no contract commitment. I should not have to continue to pay for something I do not want or be FORCED into something I do not need.
