Constantly calling. 4times a day

I havent answered this nm but has anyone else

Dont want calls feom this nm

They are calling me several times a day. Who the hell are these people? I'm getting very irritated and of course they call me when I'm at work.

They called 6 to 7 times per day.  I finally answered and they asked for someone else by name and I told them they had wrong number.  They kept insisting I had inquired about weight loss program.  Told them not to call and they still continued to call until I blocked them.
