OK Furniture a subsidiary of the Shoprite Group - the worst customer experience ever

I bought a fridge freezer at OK Furniture in Eswatini mid August 2023. I used it twice and the third time I switched it on in December on the 23rd it did not work. I reported this mishap to the salesman expecting after sales customer support. To my horror he flatly refused to attend to the matter saying he will send a technician to fix the freezer after the Christmas holidays. This after all the meat bought for Christmas was spoilt. I demanded a refund and the shop refused and eventually their parent company Shoprite Group sent me a ("threatening and intimidating") legal letter with wrong dates and sequence of events telling me to fetch the fixed freezer within 20 days or they sell it. Like seriously which company disregards a consumer's rights with such patronising arrogance. Through my lawyer I have for the up-teenth time told them I would not want to deal with them again and all I need is a refund.
