Frequent Service outages

I live in Renton Washington.  We have had a number of service outages in the past 6 months.  They have ranged from an hour to 5 hours per outage.  I cannot find a way to actually discuss this with someone from Comcast??

I believe the best solution is to contact and file a complaint with the Washington Utilities and Transportation commission.  It is sad that Comcast does not provide and easy way to discuss these sort of issues with them directly.
