I keep getting calls from 800-945-2288 saying they are Comcast. A person whose accent is so thick that it is extremely hard to understand starts grilling me about how many connections I have and how old is my router. Comcast should know the answer to these questions. If this is a legitimate Comcast call please have people that can talk clearly and slowly. If you are unable to do that, I guess I will continue to hang up !!
