WORST ONLINE EXPERIENCE WITH MAKRO

I placed my order online, they failed to deliver. I kept on receiving messages that the delivery was called because they couldn’t get hold of me yet I have not received any email or sms notifying me of delivery. One morning I received an sms that my package would be delivered, I received the drivers details, few minutes later I received a message that my delivery was cancelled cause they couldn’t reach me, I called the driver and he indicated that he had to leave my order at the store because they gave him an empty box. I kept on calling Makro several times without any assistance. I have now requested for refund and I am still not attended, I’ve called, sent emails with no help. I want my REFUND!!
