Terrible after sales service

I am very disgusted with Makro's after sale service. I bought a fridge with 5 year guarantee and after 3 years it has given up. I called the Call center on a Saturday 28 September and was told I would be called back that afternoon. I heard nothing so I called back on Monday 30 September and managed to give in all the details for the service and was informed that I would be contacted in 24 to 48 hours by the technician to book a time for repair. I patiently waited the 48 hours but to no avail. I called back on Friday 04 October to be told that there is a back log and my service request will be escalated. And I would be contacted on Saturday or Monday. Meanwhile my months groceries that were in the fridge and freezer have all defrosted and gone off and I had to throw it all away.. It is now Tuesday 08 October I have had no call from the service department nor have I had my fridge repaired. I called back again and was apologized to. And once again I have been told my request for repair has been escalated and should be contacted by Friday with a job number. I am still sitting with a fridge that doesn't work since 27 September and a month's worth of groceries in the bin. This service is disgusting.
