Got the same call, called phone provider & they told me it was a scam. They don't want the caller found as they (the phone companies) make money off of scammers.
I got twice of the calls from this number today and read all the messages on 800notes. Just curious why the law enforcement office can't trace the caller from the service provider and do something about it to prevent the crime!
I've been getting calls from these clowns. Two today. They give up if no one answers. They seem to probe with a call from an unidentified caller to see if someone will answer. Then the other calls follow.
Found out that I can selectively block numbers. And block anonymous callers. Exquisite. They change numbers periodically, but one can check 800notes for the numbers these individuals use. There is a particular curse in Indian one must deploy when dealing with them.
