This number calls all the time and never leaves a message.
When I call back it says "all circuits busy please call again later"
I really am starting to hate this crap
Same thing just happened to me. I believe they're just checking cell numbers to see if they are good then selling them on listed to spammers who text messages. If there is a way to shut these people down that would be good. I'll add them to my do not call but not sure that applies to cell phones.
They hung up as soon as I answered by the way. That is why I think this is a phone checker who is validating cell #'s then selling them.
