Disappointing quality fridge by Samsung

We bought a Samsung fridge/ freezer in 2017 on Black Friday almost exactly 4 months later I get home to a freezer that has defrosted and had to discard a lot of my meats. When calling Samsung South Africa the next day (Thursday 22 March) they logged a call and said they would get back to us, it never happened so we called again later the day just to find out they just booked us for the Saturday not even contacting us. Today I phoned again asking them when on Saturday the technician will be coming as I need to make arrangements for someone to be home, again they told me they can’t give me an exact time but will speak with the technician to give me a call. A few calls from me and my fiancé later, we found out the company contracted to come and look at the fridge have closed at twelve today and they still have no time for me and as an added bonus the technician does not operate on weekend so I was rescheduled for Monday. Absolutely pathetic, I have had to throw away perfectly good groceries and I am without a freezer for a unknown period. A item bought at an expensive price as an investment but could not even reach a 4 month life time. Very disappointed in the product as well as the service in resolving and issue that falls under the warranty.
