I will never order from Makro Online again

I will never order from Makro Online again. This is the 4th time that I have ordered something on Makro Online just to get an email days later stating that they are processing my refund. If you go om your Makro Online Profile to view your order it states that the order was cancelled & a refund is in process. No explanation, no notification that the item that was ordered is out of stock, therefore cancelled, nothing. The previous time this happened I phoned Makro Customer Services and the lady told me that she can't help me to find out why my order was cancelled because I have ordered directly from the supplier, not directly from Makro, which is absurd. It seems that they have no record of anything ordered through Makro Online because if there were records, she would have been able to tell me why my order was cancelled. There is just no correspondence from Makro in any way. You look forward to receive your order just to be notified that you will be receiving a refund with no explanation whatsoever. I needed the item I ordered & now I will have to go from one shop to the next hoping I will find something similar to what I have ordered through Makro Online.
