I keep getting calls on my mobile from this number. it is for a roller door compnay and even after I have answered once to say I am not interested I still keep getting missed calls from them. How do I stop this?

They call and hang up - never leave a message.

I have spoken to Mr. Gary Thomps about a collection. I informed him I was at work and will take care of the matter once i got home. he began to call my job and harass employees. He also started to cuss my boss out demanding that i pay the debt, which I didn't have at the time now he's making threats that he going to make lose my job.

They keep calling all the time
