Slow Inefficient Unacceptable Service

I purchased a refrigerator on 31/12/2014 from makro crown mines,delivered on 9/1/2015.3 weeks later 4/2/2015 the fridge stopped working.Morning of 5/2/2014 I personally report this to makro (note: no manager available at the fridge section).I also visited the store again on the 7/2/2015 with no success (manager at the fridge section not available again).I have been liasing with makro and samsung every day thus far,to escalate this urgent matter.Let it be known that I had to make various calls to staff of makro and samsung prompting them for feedback before getting any from both parties.It is now 10/2/2015 and once again I had to contact makro to get feedback on this matter and was advised that samsung is offline and it is not yet resolved.I am truly appalled at the service from both parties.Makro is responsible as this item was purchased from their store.It is 6 days now without a fridge and I have a husband who is diabetic and is on insulin which needs to be kept in the fridge.I now want this item refunded not replaced.
