Refuse to comply with the Consumer Protection Act

I have purchased two tp-link ****les from Incredible, both times, within six months, the charge point breaks and they were unusable. I took the second one back to the Rosebank store, to be told that company policy does not replace broken items after 7 days. I referred them to the Consumer Protection Act which points out that consumers can select to have a full replacement of any product that stops working within six months. They told me to mail my complaint to them, which I did. No response. I then whatsapped them, went through the story, and was told 'thanks for contacting us and have a nice day further'. Really bad service, besides the fact that what they are doing is *******. Won't be purchasing from them ever again.
