Faulty vacuum cleaner not yet replaced at Makro Woodmead

I purchased a vacuum cleaner and within 2 weeks it started losing power. Spent 2 hours at the Makro Woodmead Returns section on the 29 August 2020 and still waiting for an answer. I requested for the vacuum cleaner to be replaced. Reference number: ***. After reporting the fault, the Returns section tells me to follow up with the call centre. When following up with the call centre they tell me to phone the Returns section at Makro Woodmead. Furthermore held on and got cut off when phoned the store just now after waiting for a while. Shocking how something so simple cannot be resolved timeously. Very frustrated and disappointed. All I need is the vacuum cleaner to be replaced.
