How to find out when ur contract is up? I am moving out of state and got 1GBit symmetrical Inet now

I need to know when my contract is up. It's been a few years. I am moving to ouside of Sedona, AZ and already have a symmetrical 1Gbit FTTH residential account installed there at my house from another provider.

If I wanted high speed Internet here (and I did) Comcast (only provider at the time) basically forced me into getting a Business account at my house as they refused to recognized our three apartments & my house as residential...even with documentaion from the city stating we are dual zoned. In their computers Comcast has our address shown/listed as within a 'Business Park' here at the local airport in Sandwich, IL. I am moving and already have a 1Gbit symmetrical FTTH connection setup at my new house and need to cancel this service.
