Money paid, no delivery, no stock, no response!

I made an order at Makro online on 29 Sep for R22 500. I phoned Makro to follow up my order as I have not been receiving the purchase or any response. It is the most undesirable experience as Makro answered my phone call but keep transferring me to all the other department within Makro and I have spent over 30 minutes trying to talk the relevant person, but without success. Thereafter I emailed Makro online but also no response. Here I have just one request to Makro is simply to cancel my order and refund me the full amount soonest!
