Your local WFTV television news program reported on their "investigation" of Comcast just this past week. Here's a link to the story:

While it's fine to make/share complaints here on TOTV, this won't get you any resolution to the problems you're having with Comcast. The proper way to file a complaint is with the State's representatives. There is info in the above link that shares where you should properly be making your complaints. I know that when I filed complaints with the NYS (where I live) Public Service Commission (once re: landline phone problems and again re: brief but frequent disruptions of electrical power) I immediately had better service from both the telephone (Verizon) and power (National Grid) companies.
It's just a suggestion. But, I firmly believe in filing a formal complaint against a company if I expect to have any chance of resolution.
