Made in China to Break in South Africa

I had purchased a microwave 2 years ago.In the first year it gave me an SE Error of which I had taken it back ....a year later 5 months out of the warranty the same problem arose.I explained to nadeem k at samsung that even though I am out of the warranty the repair should have lasted longer than a year and if it was fixed why did it happen again ....I was told that at least I still got a year out of it and that he doesn't know how I use my microwave.I then requested for his supervisor to call me of which I have still not received and he emailed house and home with a final outcome without me voicing my concern....This is horrible service.I now had to call in again this morning and Beckha said that he would request a report from the service centre and take it from there....Different people doing different things...Bechka is amazing..I gave you guys in the first year a chance to honour the repair that should never have happen I feel now that you guys should at least honour my repair
