Makro/Wumdrop delivery

Purchased a patio set online with Makro. When I called to inquire about delivery the Makro call centre advised that Wumdrop will be delivering my furniture. A Wumdrop courier arrived at my house with just the table, which is not even half of the patio set. The courier advised me that they will deliver the rest of the set later in the day. This hasn't happened and it is already after close of business.

When I try to track my order on the Wumdrop website it says that the stock has been delivered. There are no Wumdrop contact details so there is no way of finding out where the rest of my patio set is.

When I call Makro regarding this matter they say that the full patio set has been dispatched with the courier.

I see online that Makro has acquired the Wumdrop brand. I sincerely hope that my stock is safe and traceable because if it is not at the Makro branch and not at my home then it must still be with the courier somewhere? A thought that makes me uneasy seeing as the stock is worth 10k.
