LG Product not repaired and didn't receive it back

On 29-10-2019 I purchased a LG PK3 Bluetooth speaker at Makro Vaal 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. I took this to Makro customer care services because they claimed it came with a 2 year warranty. 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 (via 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 after the January call. After various attempts to contact Makro, I still have not received my faulty product or a repair (23-06-2021).
