I've been called 3 times by this number.This is a number that comes up on caller ID as Martz Broadcast with a local are code. When I answered there was the usual pause in which it was obviously a telemarketing call. After I said hello , His immediate response in a non American accent was, "Hello I'm from technical support." He didn't state the companies name or anything. I simply said. "please remove me from your call list. He instantly hung up. Its odd to me that I didn't start getting telemarketing calls until AFTER I signed up on the "DO NOT CALL registry.
