Makro, worst online shop ever

I ordered gifts for clients that I need to deliver on Monday online and they were supposed to be delivered today. Saturday. I asked the online department outside the shop where the delivery is and they could not assist in anyway. Even me giving them a tracking number, they had no idea. I asked a manager to call me and assist. When the manager called, she informed that that the system cancelled the order and no one informed me and they also don't really know why. Sorry. This means no gifts a day before I have to deliver them. They simply cancel the order and do not offer any proper solutions or alternative remedies. This is the biggest let down and worst service I could have have received this time of year when I needed the quick service. They excepted the order, took the money, created expectation and then simply dropped me on the day of delivery. At what point will they take responsibility?
