Charge for tech to come out and activate my phone

I had one solid week of troubleshooting with Comcast on why my digital voice was out for two weeks, no access to phone. The only resolution was tech coming out to the home and he got it started. I have a $100.00 charge that needs to be credited. I worked with several people on the phone and no one could get it started until the tech came out and did something. I need my accout credited ASAP for the $100.00 charge.
