Who called from 6173608747

Past 3 days
Everynight

Called the past two nights. Caller ID read BLACK KEYZ.

Called me last night, it was only static. Today when I got home there were a few strange messages left on my machine. They just called again there was a loud screeching sound that blew out my phone speaker. I'm still shaking... DO NOT PICK UP!

Do not answer

Calling my home phone constantly, hangs up on machine... Also has Black Keys as name of caller. It's getting annoying, at least 3 calls per day
