I've had no trouble with Comcast in my area in service or support. My problem with them is that they're colluding with AT&T to keep internet prices high and upsell everyone onto bundled plans, when all I need is internet (not home phone and TV service). Thus they charge $20/mo for 3Mbps, $50 for 6Mbps and $65 for 25Mbps unbundled internet, and AT&T charges roughly the same.
