Poor customer service - Makro online service

I placed an order through the online service. I paid for the order in full, and I was advised that the order would be delivered in two days. The order was for alcohol and soft drinks as I'm hosting an event. Just after I placed the order, I received an email to advise me that one of the items I ordered, was not available and out of stock. The second response was that the order is split into 3 orders and deliveries. Makro accepts the customer to be available for 3 deliveries but only one online order was placed from one department. Then I phoned the Online customer care Centre, they were unable to clarify and the manager was busy and was not able to take my call. The manager cannot phone me back as they are an outbound call center. I then managed to speak to a manager at the Strubensvalley branch(Lesando) and our call was cut. I then phoned customer care to reconnect with the manager, 2 hours and no callback from the manager, I had no idea if my order would be delivered in time. Worst customer experience
