NO SERVICE AT ALL FROM MAKRO

We ordered a fridge freezer online and paid for it. It was delivered on Tuesday 23. The delivery people just offloaded and rushed off. I signed for it stating that it was still packed when they left. It had a large dent on top of the righthand door. We informed Makro right away and have been given the runaround ever since. You can only phone 1 call centre number. all numbers go to the call centre. We got a mail saying it was being collected on Friday 26 and the replacement would be delivered on Saturday 27. Nothing happened. No communication from Makro at all. I have called the call centre every day. It has been escalated and taken to management. The last call took 15 minutes because I asked to speak to a supervisor and was just put on hold. No response whatsoever. They are a disgrace. They obviously just want us to go away. How does one deal with a company like this? I even tried calling Massmart and their numbers are not available.
