Online purchase promise not adhered to

I ordered some stuff online and the delivery was due to occur 2-5 days thereafter. On the 4th day I called Makro to ask what time it will arrive so that I could arrange to be there to receive the delivery. On this day, they mention that the delivery will not go through due to one item being unavailable. I said fine please remove the one item and deliver the other 10 or so items. The new day for delivery was then 3 day later (day 7) which is 2 days later than the original 2-5 that was mentioned. I have meetings booked for this date and I now have to reshuffle meetings and jump when Makro calls to rush to the office an receive the delivery. Throughout the period neither Makro nor their courier company call once and if I did not call to find stuff out, I would not know what is happening and when to expect delivery. the most frustrating part about this issue in not the unavailability of stock or the late delivery, but rather the fact that Makro did not call or notify me about any of these issues that they are experiencing on their side. There are problems that will always occur in life however, through communication, frustration,confusion and anger can be prevented.
