Appoling customer service

I purchased a ryobi pressure washer on the 15 of November 2023 and it stop working during December when I returned the product in January I was told it would be sent to repair so I waited 22 working days for it 2 be fixed. Upon receiving an sms that my machine was ready for collection I went to the store only to fined the product in an non functional state and was told that the company count repair the machine unless I paid a 1000 rands and the I didn't even use the machine for more than 3 months .I was told upon purchasing the machine that it has a 3 year guarantee. I am so unhappy with the level of dishonesty I received from the so called customer service and guarantee.
