Appalling Service - Makro Online

I placed an order for 10 laptops on the 17 of April, order was paid for and confirmed. Delivery was scheduled for the 29th of April. On the 2nd of May, in a state of panic, I called Makro to check if they had delivered the laptops and I wasn't there to accept them. They couldn't answer me and they said they would email me. They did! I reminded them of the order! I received different emails with different reasons as to why they were canceling the order. To say I'm displeased is putting it mildly as I now have 10 learners without laptops! And they are excited to process my refund which I also have to wait another 7-10 working days for it to reflect on our account!!!! Really Makro???
