Unhappy customer

I bought a defy side x side fridge from makro Springfield in December 2023, I’m so ****ed off that a few days later it started making a terrible noise, I logged the first call with makro and they sent out a technician to sort out a brand new fridge, however that technician made the fridge worst, so I approached makro again and they sent out another tech who stuffed it up more. Now I’m up in arms with both makro and defy and not getting any joy from both parties, this is my third log and I have informed defy I want my monies back. It’s been about two weeks now with no joy from them. Staff was eager to argue with me including the sales lady at makro

So as per defy they say they gonna send a qualified technician which means the two that came through where unqualified
