We canceled service and returned our Comcast box to the local office once a local WISP became available. A week later, a bill arrived in the mail charging us for the box. Apparently, the billing system doesn't first check the equipment return system and it took 45 minutes with Customer Service for the barely trained CS agent to figure out how to go off script and recognize the equipment was indeed already in their possession. After years of being over charged for under performing service, I can only hope for more WISPs to spring up and eat Comcast's lunch.
