Keep missing the calland they don't leave a message. I don't try to call these numbers back.

It's the Arthritis foundation. If they hadn't called me multiple times a day for days on end, I probably would have bought one of the lottery tickets they were selling!

This numbers calls me 2 to 3 times a day for days on end.  Then it stops for a while, then starts up again!  They never leave messages but it gets logged on my voicemail.  Ridiculous!
