They call constantly...up to 8 or more calls per day. Today I finally answered with a dull "Hullo." I remained quiet and there was no response. A few seconds later, the line went dead. Ugh.

They are relentlessly calling 10 to 12 times a day, when you answer they hang up, this IS harassment.

They call repeatedly, and I want them to stop immediately.

I'm receiving calls from this number almost every hour until 8 pm, but I've never picked up the phone when they call.when  I call the # back an automated message state "none of our representatives are available, but will contact you again in a day or so".
