i just got a call from this number; i said hello and they hung up. I re-dialed the number and nobody picked up!weird

this nbr keeps calling,but leaves no message,please pull his account

just got a call from this number too.  Same, same.  hangs up when I say hello.

I have been receiving calls from (604) 637-6340- keeps hanging up when I say hello.  Called the number and a recorded messages says it is an outgoing number only....impossible to receive calls at this number.  I guess I will get it blocked.

(604) 637-6340 also called and hung up on me
