Experienced the worst Customer Care service from a big brand

Firstly, I rated my review 1 Star because there is no 0 :-((( On 29-10-2019 I purchased a LG PK3 Bluetooth speaker at Makro Vaal. It came with a 2 year warranty and seemed to be a great product. Then on 01-10-2020 while charging the speaker smoke started coming from the connector and something was burning internally. The cable was the one supp**** with the speaker and it was connected to my phone USB charger. Two months passed and in December I was contacted telling my that the cable was not covered by the warranty and the repair cost for the speaker was R1600. This is ridiculous because the speaker cost me only R600. After reviewing this objection, LG (or Makro) came back to me with a revised price of R1300. I refused to pay for the repair when the fault was clearly a product fault and not caused by negligence on my part. makro told me they would return the product and I could collect it from them in January. After various attempts to contact Makro, I still have not received my faulty product or a repair (23-06-2021). I used to consider Goldstar and now LG a top company whose products reflected quality and good service, but I've change my mind about that. If after sales service and trust of warranty cannot be expected, I'm better off purchasing other brands cheaper and equally reliable products.
