Another number from the lowlife callers..... Comcast and the government apparently are sitting on their collective thumbs. This shows as a invalid area code. Why in the devil does Comcast not block these calls knowing they are phony? I have to wonder who is making the money off of this? Am I maybe expected to start using the paid services to find and get rid of these people who seem to have picked me from millions of telephone users to call constantly? Something is wrong here. These 'cold callers' don't waste their time and efforts just for the fun of it. Trace the money and you'll find someone that expects rewards from these efforts. Do we have a case like those that developed the virus to sell the cure?
