Makro Defy fridge endless problems

I purchased a defy single door fridge from makro end off 2019 with a 5 year warranty, they delivered the fridge, the door rubbers were not properly installed and was looking very untidy, could see rubbers sticking out, we had told makro and they exchanged it for another same fridge, 2021 November 29th the fridge wasn't cooling, *** defy guy came out, replaced termostat, 2 months later 1 of February 2022, I am in a problem again with this fridge we're my food and milk is getting spoilt, the fridge is building ice at night and defrost during the day, water droplets inside fridge, I am not sure what kind off cat and mouse game this is but it is not acceptable, I called in, got another ref *** defy guy will contact me again, in a period off 2 years, is this normal to go through this kind off stress after purchasing a new fridge, I gave defy a chance to fix it first time but not again, I'll like makro to please refund me in full so I can purchase another fridge, am very disappointed as I can't keep on going and calling and repairing a new fridge, it's like buying a new vehicle and it's breaking down in 2 years, am disappointed with defy as well. Please look into this matter soonest as a defy technician will be once again visiting mee to perhaps do a repair.
