Bad service at customer service

I bought a Ryobi Lawnmower in November 2018. The lawnmower was used only four times since purchase as we had garden services. The machine stopped working as i used it. I took it back to the Game store in Nelspruit where it was bought, in the original packaging and the till slip. The lady at customer services informed me that the machine needs to be booked in for repairs as it was older than a year. It clearly states on the box that the machine got a two year guarantee. Nobody ever informed me that the guarantee is only a year and that it needs to be booked in for repairs after a year. I was also informed that the suppliers only opens on 07 January 2020 and I will only get a response after that. Needless to say I had to leave the machine with them as the matter could not be resolved. I really feel that i paid for a product with a "false" guarantee. They also just looked at me when I asked them what I must do in the mean time. They are full of promises but when it comes to after sales service its a no go. I feel that just wasted my money.
