Guarantee not upheld by Makro Pietermaritzburg

I purchased a new genesis verimark cyclone vacuum cleaner on 9 September 2017. The vacuum started to trouble on 17 August 2018 just before the one year guarantee has expired. I took into the store and showed the box where it clearly indicates that the product is guaranteed for one year. I dealt with Denzil Van Der Merwe and Cody Ramlatchman who agreed that the product is still under guarantee but said it had to go for assessment and repaired. Clearly they don't understand what a guarantee means in the retail world as they are treating a guarantee as a warranty. Makro needs to educate their staff on the difference urgently as they are creating very unhappy customers with their shoddy service. It is now a week later and there is still no news from them and they promised to contact me on the Monday that has passed. They need to stop false advertising if they not willing to uphold their promise.
