Hung Up before I could answer. Must be a ROBO

Left no message but unwanted calls

I have been receiving calls from this number over the past few days. This last time I got a call, I waited until my cell was no longer ringing ....Then went to that # on my resents list, scrolled to the bottom and Blocked that number. I am sure they will just start using another # to call me from but I'll just block that one as well....  and so it goes........

Well it looks like this number is starting up again, judging from the last entry. One ring and no message.
