Homechoice harrassment

Never ever ever buy anything from Homechoice. I bought from them once and had no problems with the order but since then they keep on harassing me. I get weekly calls from them, sometimes 3 times a week asking what else I would like to buy. In the beginning I asked politely to take my name from their list and to stop calling me but they just don't seem to act on my requests. This morning I had to ask someone for the 6th time to stop calling. Surely a company has to take a customers name off when requested due to the POPI act. This is unacceptable and total harrassment.
