Request to remove comment of phone number

I am receiving up to 3 call per day on my mobile and work.
It is in relation to an accident I had last year, I had no injuries and the other party paid to repair my car.
I am being repeatedly harassed and have to explain everyday that I do not require any compensation.
I received three calls yesterday and two today, when I block the number they call again on withheld.
Thus is from an accident from May 2014!!! I was Not injured and I would like to know who is passing my personal phone number around and also my WORK number, which is becoming a problem as I am not permitted to receive personal calls.
This must be an infringement of my confidential information!.
PLEASE STOP!!!!!
