Nightmare experience purchasing online from Makro.

I have never had a worse online experience than with Macro. After 7 days after paying my order and tracking the order (which stated “order in process”), I received an email stating that my order has been cancelled - and they hope I enjoyed my experience shopping with Macro. No explanation, no refund? I called Macro many times and my call got cut after holding on for ever - every time! I had the same experience with the Macro call center. The order status when I track it, now states “order cancelled”. I want my money back in my account immediately! Obviously I will never shop with Macro again or recommend buying from Macro.
