Pathethic Service

I purchased and paid for an item online with Makro, a few hours later, received a message saying my order was cancelled due to no stock, And then a few hours later the item is back online and at a higher price. This is unacceptable. Store advised a price online and probably realised their error when i placed my order and then lie about the product bein unavailable and then few hours later edit the price and stock is available. Is this the kind of service that Makro offers. Lie to their clients. I dont want a refund, I want the item at the discounted price that I paid that was online.
