Bad customer service and false sales

I bought a refrigerator on the 27th of Nov was told it's out of stock i can pay for it they will call me once they receive stock. Went to the shop the next day they confirmed they haven't received stock. When i left the shop i received a call from the shop to inform me that my fridge arrived but was sold to someone else i need to wait for stock to be delivered again. The next day that is on Friday 29 Nov i went to the shop i went to the shop and i spoke to Enkie who told me she called me the previous day and there was no answer from me. She said fridge is out of stock but they will make a plan. I waited for their call i called every day and given excuses. I called on the 9th of Dec spoke to Enkie who confirmed that on their system its showing that stock is on its way. I waited for her call but nothing. I called Wednesday the 11 Dec Enkie said latest is Friday. I called Friday morning she said i must come to the store. When i arrived there it was 12:30 i waited for her she only attended to me around 2:30. She told me i can come go fetch my receipt and come back. On my way to fetching the receipt she called to tell me that the fridge i bought is not available there's another 1 available but i need to pay r500 extra for that other 1 of which i refused and in still waiting for my fridge. Im disappointed by their customer service she she kept on saying she will call me but ever since i have never received any call from them. Hifi corp needs to revisit the consumer protection act.
