Ryobi's 1 Year Guarantee - Consumer Complaint for MAKRO - Head Office

I bought a Ryobi Circular Saw in November 2019, however I had only opened and used it once during the Level 5 lockdown. Upon using it it started to spark on the inside, this was after a few cuts I made on wooden laminate flooring tiles. I immediately switched the machine off and waited till it was possible to bring it in to your returns department at your Cornubia. They told me that it would go in for an assessment although it has a 1 year guarantee, which I agreed to and signed off on it, however I am disturbed to find out that I am quoted for a repair which leads me to believe that I maliciously damaged the unit. That alone is disturbing. So I'm to pay for a one use unit and then pack it up and forget that I bought a product which is backed by a 1 year guarantee. I'm not happy with this service and will appreciate a prompt response on this issue.
