Who called from 8583975346

I get a call from this number at least once a day. No idea who it is. They never leave a message. So, I just let it ring.

Call, no msg. left, CID San Diego CA. Just because we're in that area, maybe they think we'll answer an unknown number??? NOT. Will block if it calls again.

Sur 'nuf, it called 2 more times, CID San Diego CA. Blocked it after 2nd try & no msg.

Keeps calling even tho blocked months ago!  Shows on CID when I ck. Have the Panasonic phone that will block 250 #'s & allows "no ring" for blocked #'s. No idea who or what it is.
