According to them they are home telephone company name "Comview"  Scam.  Wouldn't allow me to speak to a supervisor or tell me why they are calling.

Got a call from this number today, but it was prefixed with 011 to make it look like an international call. When I answered, there was no response, just dead air.

Just another low class job nothing but just annoying people.  Usually cheap labor does this type of job.

This guy keeps calling. Just silent when answered. Is there any way to block this call?

Third-world India mushmouth called on a Sunday afternoon.  Asked why he was calling on a Sunday, said "because we are open on Sundays."  Loser.  I suggested he become a chai-wallah (tea seller) as this would fit better with his intelligence level.  It would be so, so good to permanently disconnect telephone service to third world countries.  No one wants to hear from them anyway.
