Extremely poor delivery of promised refrigerator

I purchased a Defy refrigerator June 2014. Since April 2015 I have been without a working fridge. Technician came three times. Could not figure out why freezer does not work and fridge freezes. Sent a bar fridge as a loan!! Promised to replace. defy with later model. Now told to return to Makro for money back: at this stage replacement is more expensive and onus is now on me to get replacement. Mr. Dianney at Defy requested proof of payment plus proof of extended warranty. Supp**** end May. Every week I hear:,we have no stock!! Terribly disappointed at promises made and left unfulfilled., imagine 5 weeks without a working fridge or freezer!
