Non existent online delivery service and customer support

I placed an order online for two items. A dishwasher and some dishwasher soap. The dishwasher was deliver on time, the soap however was not.

When we hit 30 days without delivery I called Makro to cancel the order. I was assured the order was cancelled and that this would be sorted out.

A week later nothing had been resolved, I called again, they had no knowledge of my previous call. I again requested the order was cancelled and that I could be refunded. I was assured this would happen. I also requested I could speak to someone higher up to make a formal complaint. Some days later someone higher up called me and we went through this whole debacle again.

Much to my surprise a courier arrived and was trying to deliver the item which I had already canceled twice. Since I had cancelled the item I refused delivery.

We are now on day 54. Nobody from Makro has bothered to get back to me or to give me any information. Every time I call they cannot give me information and their supervisors are not available. I even tried to call Makro's head office out of frustration, I explained the situation to the operator and was transferred back to the useless customer care center.

I'm extremely upset with the complete lack of any help.
