MAKRO ONLINE SERVICE SUCKS!!!

I ordered a HP Tablet online on the at the end of July and haven't received my order. I had by mistake not changed the delivery address when I processed the order. However immediately after I finalised the order I realised my mistake and called Makro to alert them to the error. There isn't an option to correct anything on the order once it's in their system. I was told that I should not worry, they have corrected it as per my call. On my profile the address remained the same. I called multiple times thereafter and was assured it was escalated to the despatch. Subsequent to this, I received an email stating that the package was on it's way for delivery and once again the wrong address was appearing on the email. I called again, frantic this time that the item is going to the wrong place. I was then told if I did not receive a PIN, that the item was actually delivered. But they are fixing it and will get my order delivered. Many hours and many calls, to date no one can help with either refunding me or getting the device delivered. The worst part of it all I cannot seem to escalate higher than a supervisor!!! How very frustrating is that. Each supervisor that you speak to promises to sort it out, only once was I called by someone. MAKRO you service sucks! Refund my money and we will call it a day!!!
