My local technician arrived within the time alloted and was great. I don’t know yet if his fix solved the problem but he did find that I was receiving too strong of a signal. He gave me his personal number so I could follow up with him and asked me to keep a log if the problem reoccurred so he would have sufficient data to troubleshoot. Really nice guy.
I’m also impressed that Comcast monitors the social media. I received a good comment on my blogger post and via Twitter so that I could contact someone to help me further. I will only do that if I need to as I’m satisfied with my local technician at this point.
