Cannot repair my 20,000 rand fridge

I bought a top of the range Samsung fridge from Hirsh's Ballito about 5 years ago. November last year the freezer section packed up. Being a respectable company I thought ,I sent it to them for the repair. They took the fridge to there workshop .They quoted me and as the fridge was not under guarantee I agreed to pay. I asked the manager Vishe if there wasn't a guarantee. He said no.I since found out there was a 10 year warranty on the compressor. He refunded me the money. I still haven't received the fridge back and they now tell me they cannot fix the fridge and2 people from hirshes management have said that these fridges only last 5 year. Funny how they give a 10 year warranty for a 5 year lifespan. I have spoken to hirshes and Samsung and they say I must buy another fridge.R20000 rand every 5 years I think not. I am disgusted in the behaviour of both parties. They also damaged the fridge ,My floor and cupboard .They now want me to take the fridge to another repair centre. All I want is my fridge back in working order. Ashley from Samsung also proved to be very unhelpful in this .Can anyone advise me where to go from here
