No Warranty support from Makro

I purchased a Trimtech ****eater on 3rd February 2025 from Makro Amanzimtoti. The machine worked for less than an hour and started overheating. This is obviously a manufacturing fault - one can hardly destroy a machine like that in less than an hour. Makro's policy is that because it has "worked" it must be sent for assessment. Really at only 7 days old! How do you find out if it is faulty if you haven't used it. This is regardless of the inconvenience of being without the unit and having to go back to Macro to fetch it when it is eventually returned/replaced. This is pathetic customer service and the only answer I get from the Makro staff is "Makro Policy"
