Makro damages goods and expect customer to pay

I bought a chainsaw on special in Aug 2020. But did not use it till Oct 2020 since I did not have a gardener. We used it for 2 days after which it did not want to start again. I took my gardener to Makro so that he could explain at the returns department what was wrong with it and they said that hey will send it for repairs and it will take 4 to six weeks. The chainsaw had No external damage. Late Dec 2020 I was notified by Makro that they had quoted me R800 to repair a broken breakcover. This was not broken the day we gave the chainsaw in and I asked the lady to have her supervisor phone me as I would. Not pay for damage Makro did. Till today the 11 Jan 2021 nobody has phoned me back yet and the chainsaw was at Makro for 3months yesterday
