Caller type: Unknown
This number showed up on my caller ID today 7/29/14 @ 09:20 AM. I had previously blocked it, so the phone rang once and it was blocked. I called the number back and it shows as not in service. I get so many of these type of calls it is unbelievable; most (when I answer and feel like messing with them) are about home repairs. I don't think there is any way to stop the calls, as the numbers are somehow spoofed.
