Munnik,Basson and Dagama harassment.

Please take note that I am being Harassed by Munnik, Basson and Dagama call centre staff. I am being called twice per day, everyday. I have made it very clear that I am a Medical Professional worker and work in Theatre. I cannot take or make personal calls when I am monitoring a patient during a theatre procedure. I have a standing arrangement with Munnik, Basson and Dagama to pay R once per month on the 1st of every month. I am the breadwinner in our household and all the expenses fall on me. Please can you stop this harassment. I get paid per patient by their medical aids. Some months it's ten patients ,some months it's twenty patients. This figure varies and therefore I can only commit to R per month. Please can you understand my situation and stick to the agreement.
