Rude Thembakazi Nuse- Home Choice

I have changed my number several times now and this company won't stop calling me. I try to be as patient as I can be but I can't anymore. I have a private number that I have and how they get hold of it I honestly don't know. They have been harassing me emotionally and I really cannot take it anymore. I kept my number private for my dads oncologist to call me in case of an emergency but home choice just doesn't stop calling me. I almost dropped my baby today when a very rude Thembakazi Nuse called me today insisting I gave them my number. Why the hell would I want to give them my number when they the most annoying company. Im tired now really, what else can a person do?
