Avoid Makro Online at all cost

I tried to shop at Makro Online. I was able to transact until I tried to go to the check-out. It gave me a message about the delivery and wouldn't allow me to complete the payment. I tried a different browser with the same outcome. I contacted Makro online and phoned their call centre logging the problem. They couldn't explain what was wrong but promised to come back to me. Almost a week after I tried to initially make the purchase, I had to phone again to enquire what was wrong. Finally, somebody went to the trouble to find out only to tell me that the item was no longer available. At no point did the website reflect that so there was no way of telling that. I will not easily use their online shopping and their call centre is pathetic except for the last consultant.
