I've received calls from this number every few days for the last couple weeks now, never leave a message and sometimes call multiple times in a row. When I answered last it was just dead air.
I am going through the same thing with this number.. It has called me every day for the last week! Always between 9-11 in the morning. I finally blocked it today from calling.
Got a third call from this number in the last 2 weeks. I don't answer unknown calls even if it comes from my own area code of 206 (Seattle). As before, no message was left.
This number keeps calling me everyday around 9\10 am I don't answer but I try calling back and it says it's a non working number and they never leave a message either. I'm thinking of blocking the number.
