Poor sevice by Homemark

I bought a remote controlled drone for my child from Homemark. Item was returned to store 4 times in a period of 26 days. This delay in returning is only because we live 155km from Cape Town. Store Manager ( Anthony Darries ) however were informed immediately everytime, plus I sent him videos of the malfunctioning item. There seems to be a technical problem with the item. Mr Darries was asked to investigate as to a solution to the problem. He refused to do this. I then asked for a refund of my money and he refused to refund my money. I was told I could pick another item to the same value. Since there is nothing else in his store that my child wants I refused and demanded a money refund. The matter was reported by e-mail to Customer Care at Homemark head office as well. No response from them. On telephonic enquiry I was told by Danielle to again submit my complaint, which I did twice more. Still no response from Homemark head office. I bought an item which is faulty, does not meet expectations and the supplier cannot advise on how to rectify the problem, therefore I am within my rights, as per the consumer protection act , to demand a refund of my money.
