Who called from 6044954827

Reverse lookup returns nothing.  They called but did not leave a message.  I do not answer calls from numbers I do not know.

I also recieved a call from this number but didn't answer. They didn't leave a message.

Same thing- I got a call from 604-495-4822 last week and 604-495-4827 today, both times no response when I answered.

I got phone call from 604-495-4827, and 604-495-4815, I answered it but no answer from the other side.

Another annoying caller. I too do not answer when I do not recognize the number because I get a number of these calls in a day. When I call back to see who answers, their line is busy.
