Poor poor service

On Saturday 1 October at approximately 16:10pm I walked past the Show Bar in Gateway shopping centre. I had my two young kids with me, and I was in a hurry, but the sales lady was persistent. She insisted on demoing a straightening brush which I was adamant I didn’t need. Then when I said I really had to leave she pulled out a curling wand. She tested this on a strand of my hair and at first look it was fine. I felt like she put me on the spot and i felt increasingly preassurized so i purchase the curling wand. When I got home at attempted to use the want, I absolutely did not get the result I wanted that she had shown me. I have Keratin hair extensions which I informed the sales lady of, and she could visibly see. I did not hear everything the sales lady said, firstly because I am partially deaf, secondly my kids were distracting me as they wanted to go and thirdly the mall was very noisy making it extremely difficult to hear in an already challenging environment. I have sent them several emails and requests via their website and have received no feedback thus far. I have even offered to courier the goods back to them in their original packaging at my own cost for a full refund.
