Makro Call Centre VERY BAD service

I bought a dishwasher online, there are no real place where you select the address the item should go to so I proceeded to pay thinking that if I selected to shop in CPT the system would realise that the address in Gauteng doesn't match, however after I processed the payment I immediately realised the address is my previous address in Gauteng and called Makro call center to change my address. That has been almost 4 weeks ago and ever since I have made calls almost everyday and eventually asked for the order to be cancelled. That has also not been processed yet even though that was almost a week ago. Every time you phone they say "we need to escalate" and that's it. Nothing comes of the escalation and nothing happens either not to even speak of any feedback. When you call for feedback they say they need to escalate and round and round we go. So no dishwasher and no refund and 4 weeks later I have no idea of what to do to get my money back.
