Homechoice calling non-stop

Can Homechoice stop calling me I want nothing from them. I bought a heater from Homechoice years ago paid it cash since then they have been calling me to tell me about specials which I told them I am not interested now they call EVERYDAY as if I owe them ****. When I checked my credit report THERE WAS HOMECHOICE stating I made a credit enquiry on THEM WHICH I HAVE NEVER. Can my number *** be removed from their database please I'm so annoyed by this store I would never recommend them to anyone. Once you buy from them they sit on your shoulders and be a nuisance. Please remove Zukiswa Nqolobe on your call list even your letters I WANT OUT.
