What does one have to do to get good service from Makro?

I have a query about my order MAK***

Dear Makro

I am still stuck with the fan that you sent me which isn't working. I have sent multiple emails, I have logged a return online, I have reached out to your WhatsApp channel, I have left multiple reviews on Hello Peter and I am still stuck with this fan. Please give me my money back and take back your fan. What does one have to do to get good service from this company?
