Makro online order - no delivery

I ordered a large appliance from Makro, and got communication from Makro and from Wumdrop that it would be delivered on 25 November.

On 24 November I got a call from the driver to say he's outside my house. I was not home because I was expecting delivery the next day. I asked if it could be delivered on 25 November as originally planned, and he said yes it will get delivered then.

On 25 November there was no communication from Wumdrop at all. I tried their chat bot and calling their phone number but no response and I couldn't get in touch with them. The delivery was not delivered.

Yesterday I got an SMS from Wumdrop saying it would be delivered today (28 November). Again today, no communication from Wumdrop, and my order is still not delivered. The tracking portal is not helpful at all and the states jump between "order placed" "order placed successfully, pick up time between 9:00 and 12:00 today" and back to "order placed" again.

Wumdrop does not answer their phones and don't reply to the live chat. Every time I call Makro the call drops and I can't get hold of them either.
