Bad service from Potchefstroom Game

I purchased a verimark iron at Potchefstroom Game on the 16th December 2019. I returned the iron on the17th December because I wasn't happy about it. To my suprise the verimark manager Mr Vermaak and frontline supervisor Nonkuleko refused to take the iron, said that I have used it and it's second hand. But I had to use the iron in order to check if it was working according to it's specifications. Kindly note that none of verimark sales person was on site when I bought this iron. I have sent several emails to Game head office and I have not heard anything from them since the 17th of December. Do I not have the right to return a product as a consumer if I'm not happy about it?
