Dischem not assisting with faulty GHD that was purchased from them

My sister purchased a GHD max from the online store around December 2022, it stopped working recently, she contacted the dischem customer care centre, they advised her to take the GHD to the nearest dischem store. today we went to the cornubia branch, i dealt with Preston the store manager, he advised that they can't help me when anything. and i must contact GHD or take the faulty unit to them for assessment, i asked him if they can contact them on our behalf, he advised that faulty units got nothing to do with Dischem and its the customers responsibility to make contact to GHD. We purchased this hair straighter from Dischem and now we must run around to try and get it fix? so all appliances that we buy from here, when it gets faulty we must run around contacting the brand repairs?, thats nonsense, dischem is going down hill, i hope this review reaches many so they can see how you have to run around when appliances goes faulty...
