Makro and Wumdrop have ruined Christmas - no delivery, no communication

I finally today managed to speak to someone at Makro and got the name of the courier company. I can't track my parcel order that was placed on 2nd December and allegedly handed to Wumdrop courier on 10th December. The Wumdrop online tracking app has no record and the web site proudly states that customer service doesn't work weekends - not even the weekend before Christmas!! Makro hasn't got a clue where my order is and I have had no communication from Wumdrop. I needed this parcel this weekend so I will be repurchasing the items from another retailer and claiming a refund from Makro. I'm done.
