BOTH FRIDGE & MICROWAVE NOT WORKING!!!!!!!

I bought my Samsung fridge on the 2014-01-30 and my microwave on the 2014-01-17 and have both stop working. 1st it was my microwave which stopped working last year the 2016-10-18, I went to Digital experience, fourways crossing and they were NO HELP at all!! To cut the long story short, the receipt was printed for me because I had misplaced my original and after it was printed. Then they refused it help because I didn't have the original receipt, which did not make sense plus I has paid an extra R399 for the extended warranty but I was still NOT ASSISTED! Then two months again my fridge also STOPPED WORKING and I was told it's out of warranty and I have to pay. My problem is both my appliances are only THREE years old and they have already just stopped working, how does that happen?? I bought Samsung because I thought it was the best and it would last me for at least FIVE YEARS or more but I guess I was wrong. Both my fridge and microwave were not cheap, price of my fridge was R5 995 and microwave R1 700!!! Now I paid a lot for these appliances and the quality is not up to its standards. I have NO FRIDGE, NO MICROWAVE, NO ASSISTANCE, just NO SERVICE. I would like both my fridge and microwave fixed without being charged. This has been going on for far to long and I would really appreciate assistance ASAP.
