Makro online: No delivery

I ordered a package from Makro online on the 13th of November and was told delivery would be on the 15th of November, which didn't happen. Today I called their customer care and they said it's scheduled for delivery for today. The courier company they use (Wumdrop) advised me that the says the distribution centre doesn't have my order and I need to follow up with Makro. I was told someone from the DC will call me and this hasn't happened at all. I'm so upset because I've spent the past 2 days sitting at home waiting for my order. Calling and sending emails with no real help.
