Who called from 6182161307

I'd like to know as well, they've been calling me several times a day for a few weeks now!

Called, didn't leave a message.  Spam caller

I have been getting calls from this number several times a week. I have blocked the number on my phone and I am still getting calls.

This number calls me and don't leave a message few times a month.

they call several times a day or week and do not leave a message.  It  is very annoying.  I do not answer calls from numbers I do not recognize.
