Makro bad services

I purchased a printer from Makro that stopped working and logged a return on 20 July. Although I received conflicting emails about whether the return was approved or rejected, I later received confirmation that it was approved and would take about four weeks. Since then, I have received no proper updates. I have contacted the call centre several times, but no one seems to know the status of my printer. On Monday, I was told the printer was at a store and that they would call me back, but no one did. When I called again today, I was told they had supposedly tried to contact me and that the matter had been escalated.

It is now September, and I still have no printer, no clear explanation, and no proper communication from Makro.
