Can you really rely on DEFY ?

At the end of February 2015, I bought a double door DEFY Fridge from Makro. Probably one of the more foolish decisions I have ever made. I had issues with the door and water dispenser from day 1. So through Makro (who were very efficient), the Defy technician visited me 3 times, eventually, the fridge was replaced. I thought that all will be well. Well, I ask again, can you really rely on Defy ? About 2 weeks ago, the fridge stop getting cold (resulting in my food going off). I phoned Makro (again, very efficient) who phoned Defy. The expert came out last Friday 18/09. Post his visit, off I went to my local retailer to re-stock up. To my horror, Sunday night the fridge stops works, AGAIN, all this food went off. I phoned Defy myself, the technician came out on Monday 21/09/2015. All went well, for abour 48 hours. Off to my retailer I go, that is, to re-stock grocery items and meat. I could have fallen into a cave as on Wednesday, the fridge STOPPED AGAIN !!!! 24/09/2015 - Off I went to Makro, on bended knee !!! I cannot deal with DEFY and the unreliability of their products. I know full well that Makro is caught in the middle, but this is truly ridiculous.
