This number has been calling me nonstop for months. I have had them blocked so that it goes straight to voicemail when they call, as I do not answer numbers that I don't recognize. I finally got so irritated recently that I decided to un-block the number and start picking it up to try and figure out who the heck has been calling me.  I picked up this morning, and there was silence on the other end, and then they hung up.  The strange part is, when I immediately called back the number, I was told that the number was disconnected.  I googled it, and the number belongs to a company called Allegro USA Inc. in Los Angeles.  I cannot figure this out and it's driving me crazy.  Is anyone else getting this? Thankfully I am changing my number so hopefully it will stop...
