Annoying but it is avoidable (Score 1)

After self-installing over the phone, my internet was working but Comcast a week later started calling me every day to send a technician to "complete the installation". Finally they just show up to my place. I watch the guy do absolutely nothing and point blank ask him if I'm going to be charged for this. He says no. Sure enough I get billed $60 installation fee. I called Comcast and explained what happened, and they took the charge off right away. Still, it rubbed me so wrong I haven't used them since. Switched to RCN for the next place.
