I was getting lots of calls from the same number. Nasty calls. I downloaded call block probram & blocked the number. Now it has stopped. I thought your may like to do that.
Clearly Spoofing. These people have called from several different numbers. I block one they just call from another. They have left all kinds of weird messages. One sounded like a Jamaican saying my loan had been approved. He actually left a loan number but he never said who he was calling. The last couple of times someone just sat there and blew into the phone for 30 seconds.
