Irritating telemarketer who paid for my cell ph # (that I rarely give out) and calls and doesn't leave messages. There are other similar numbers it uses with the same 310 area code. I'm SURE it's a telemarketer because starting on a certain date I started getting various telemarketing calls....this number is one of them. Some leave messages, and I accidentally answered a couple of them. So it looks like my name hit some list that was purchased, which is when these irritating calls started.
