Who called from 9527771793

Keeps calling me too. Haven't and won't call it back. No messages left.

Called me 3 times already today.  Every time I answer, it's dead silence and then they disconnect.  No idea who it is or what they want.

Called today and yesterday, left no message. I will never call you back if I don't know who you are and what you're calling me for. So annoying!

Called and left no message and hung up

This number has called me at least once a day for the last week now, everytime I pick up it's dead silence and then it disconnects.  Very irritating....
