In response to the letter written about Comcast’s signal problems last week I would like to say that I, too, have been experiencing the same trouble with my system. I chatted with Comcast customer service and a tech will be visiting me on Monday, March 11. I told them of the previous letter in the paper. She was not able to help me with what I think is a systemic problem as she is only able to address individual problems with customers. If anyone else is having the same problems I suggest you contact Comcast. Perhaps if they get a enough input they will have their people look into how their system is preforming. If they can’t, I see a dish in my future.
