Worst and disgusting Makro

I have bought a Ryobi Brush Cutter in October 18 in 2018 my machine went In for repairs and has been for repairs 3 times before Covid 19 started i took my machine in i had to wait 3 months for the machine and for answers but nothing. The gears keeps slipping on the brush cutter. We got the sms and was told brushcutter been sent for evaluation. We went to the store today only to be told that they cannot help us and the guarantee is over. We want either our money back or we want a new one as your repair agent has stripped my brushcutter motor it been written all over the machine . It disgusting I thought Makro was always the best but clearly it going downhill. It very bad service. I want CEO of Makro to contact me and tell me that I get a replacement brushcutter or money back. I dont want something that been stripped that was never faulthy the gears were slipping and it was the same fault since the beginning.
