Makro online - Makro Store Wonderboom - poor communication and no cancellation and refund

I am an upset and very unhappy customer! I ordered on the 5th of December - this was a split order of 3 deliveries. Two of the deliveries were made on the 8th of December, of which you can imagine, I was ecstatic and impressed about!

Please cancel this order and refund my money!

I have been contacting customer service to escalate the cancellation of delivery 3 for this split order as I don't need the items anymore, and they keep telling me that they've escalated it to the relevant department. When I call the store, they don't pick up. The order was packed on the 9th of December, and the expected deliver date was on the same 9th of December. Status hasn't moved since.

Makro Wonderboom, what is going on with delivery 3? Where's the communication?

Cancel this order (delivery 3) and refund me my money immediately before I take legal action.
