Comcast Internet on Timberlake

I work from home and the Comcast Internet service is poor, affecting my productivity.  Comcast technicians indicate that the lines on Timberlake need to be replaced, but they seem unmotivated.  I was wondering if this is an issue for others, so that we may speak as a neighborhood with Comcast?  Just wanted some feedback.
