Who called from 3475355760

they called and didnt say anything

Why won't these people stop calling?  Thankfully I live in a country where I don't need to sit in a room with hundreds of other people wearing headsets and calling everyone in the phone book.

No. got a call too

Called at 11:05 am. I don't pick up numbers I don't know. They did not leave a message.

I donot pick up on unknown callers and have been receiving hang up calls without messages from this number recently
