Unacceptable service from Pic n Pay hyper Faerie Glen Returns

I purchased a Aim steam/spray iron barcode *** during January 2021. There was an electric fault 6 months after my purchase. The iron has a 2 year guarantee. I took it for repair with my till slip reflecting the iron purchase. They replaced the item, but retained my till slip as the refund clerk explained the they only replace an item once. I argued that I required a refund, repurchase slip as proof of the new product. She was adamant that that is not the way they operate. Needless to say the new iron also lasted only 7 months. With no proof of purchase they refused to assist me the second time. I lodged a complaint on Pick and Pay website www.pnp.co.za Needless to say I had no response. I notice they no longer stock the AIM steam iron. The person at reception said she could not assist to locate the original puchase as she would have to look through all my purchases. I have a smart shopper card ***27 4597
