Milex - bad product and service

It should not even get one star. I purchased one online from Game in January 2020 and it did not work - thermostat faulty. I advised Game in writing. I took it back to the store when I could travel the 300km to the city. About 3 weeks later they replaced it. I got home to find the same issue with the new Milex unit. I advised the store and the Milex agent I would be returning it the next time I drove the 300km to the store. The government then introduced lockdown and restricted travel - which is still in place in SA until next week. This means I cannot travel unless it is for an essential service. There was no way I could take it back. Now the Milex agent tells me that I am out of the warranty and they are not going to refund.
