Makro ****mers

I went to Makro Clearwater on the 24th May to purchase a heater. The one I wanted wasn't on the shelves so I made an online purchase on the Makro App. I made the payment immediately and the heater was delivered on Wednesday(that was not the scheduled date). Upon connecting it I realized the gas switch was broken. I called them the next day(Thursday) and the heater was collected on Friday the 30th May. I've been calling ****** Makro everyday since. I'm now told I didn't buy a heater at Makro but on Marketplace. They can't get hold of the supplier and they cannot guarantee if I'll get my money back, or another heater for that matter. Such a huge retail with so many customers, I just called their customer service and no one knows where my heater or where my money is. This is a *******, my money is gone, Makro is getting rich by ****ming us. I even made a card on that day, I just cut it into pieces and they will never ever see my money again, ever. ****** ****mers, ******.
