Hirsch's sells broken appliances

In March 2019 I bought a number of items at Hirsch's Milnerton. Spent R18 000 (which I am still paying off on) Amongst the items, I bought 2 Kebab machines (not an item one uses regularly) In August I hosted a party and an hour before my guests arrived, I unwrapped the kebab machines. The 1 was intact. The other one's heating lamp was smashed, had no spare lamp & was missing the kebab skewers. I had to serve 12 guests with one 5-skewer machine. I took the machine back the next day in it's original packaging, unused & untouched (The metal trays were still in it's original packaging & cable-tied to the posts) They insisted that they would have to send the machine to the supplier. A week later they called to tell me everything is sorted out and I must collect. On Sunday I went to the store, only to be met with a machine that was clearly repaired by the supplier, still had no skewers and no spare lamp. I paid for a new item. That one was clearly dropped before I bought it. I bought a damaged product and they want to repair their damaged product to give to me? The Manager said she will supply me with a brand new machine on Monday and have it delivered to my home. It's Wednesday. The repairs lady just called to tell me that she managed to get the missing parts and would I like to collect it. I told her that the manager was going to have a brand new one delivered to me on Monday, but she said this was not communicated to her. I called the manager and she said she will call me back in 10 minutes to sort it out. 45 minutes later she calls back saying the supplier does not have stock (Hirsch's had stock on the day I took it back. I checked) and if I come that way, I must come talk to her and she will sort something out for me??? How?? I bought a brand new (clearly damaged machine) and they want to repair their dudd and give it back to me and I must be satisfied? No-where in their store are any signs that one HAS to inspect your purchases within 7 days. The extractor fan I bought was only opened & installed last month because Hirsch's couldn't get the exhaust pipe that actually goes with it. I spent days on the phone, driving around and looking for the pipe. Even placed a special order with Hirsch's for the pipe in May. to date, not even a call from them to tell me they can't find one. I did not know buying from Hirsch's would turn into a fight. This is disgusting service. Fight with your supplier, not your customer who supported you. I will never spend another cent there in my life. And as it stands now... there is still no resolve.
