Who called from 3604601404

I've gotten several calls from this number & another similar number.  I have blocked this number now since they don't leave messages & if I answer the line is disconnected.

Same thing on my end, no answer or message and they keep calling.....quite annoying

Answered the call...dead silence then hung up....

Just got a call from this number, never heard of area code 360, looked it up to see western washington which is random for where I live. I didnt pick up, no message was left.

Just got a call from this number as well, didn't answer, no message received.
