I have just your Internet service.
The cost has gone out the roof, i am planning to cancel my service and move to a more cost effective internet provider.
I dont see a way to cancel my service online.
What is the best way to cancel the service i currently have with comcast?
There isn't a way to cancel on line. You can call, but the most effective way is to carry Comcast's equipment to the nearest local store and turn it back in to them. Be sure to get a receipt, and keep it forever. Also consider scanning or copying it; my shop uses thermal paper, which fades to a blank piece of paper in a week or so. Bear in mind you may be under a contract and thus subject to an early termination fee.
