Samsung — lodging a complain of a samsung refrigerator

good day i bought a refrigerator at makro in nelspruit mpumalanga in september 2012 i have only enjoyed the courtesy of having that fridge for only six moths and after that it started giving me problems it was forever trapping my electricity i have logged three times of my calls to your head office and they normally sent technicians to come and have a look at it but apparantely the problem it still persisting and i told the technicians that i need a new fridge because that have fixed for several times and i am no longer trusting it or either interested but they refuse to write a report about it in order for me to get another refrigerator and this thing is spoiling my food everytime and again i am going to take this matter further because this problem was supposed to be dealt with long time ago and they decided to fix there and there knowing exactly that my warranty will be finished in two years time.
