Makro customer service and product quality sucks

I bought a Ryobi brushcutter on 20-01-2016 at makro vaal (card no ********** 7, till/invoice 38/774). I used it about 6 times in 11 months before it refused to start. I took it in for repair to makro vaal on 23-01-2017. It was kept in a store room for almost 8 weeks before it was returned to me. They refused to test it before retuning it to me and it has not started or worked since. I have taken it back for repairs again but they refuse to have it booked in for repairs, I have been struggling ever since I took it in the very first time for repairs to get it repaired so I can use the brushcutter I paid for. But I have now realised that as soon as makro gets the money for the products they sell they forego of their responsibility towards customers. They absolutely do not care about customers or the quality of the products they sell. A product will have a 2 year warranty by makro will mot honour or stand by it. Absolutely the most pathetic service I have ever received.
