Had a call from this number yesterday and just ignored as it seems such an odd number. It's i.d. just says WA, USA. Got a call again today and answered and there was just silence on the other end. Added to my block list!!!!
I haven't answered any calls from this number yet, but I get a call from this number almost every weekday since 5/12/15 and no message is ever left. If I try to call the number, I get the standard phone-company recording that says the call cannot be completed as dialed.
