Confusing, frustrating.. it is just a delivery gone wrong

Ordered a bottle of Nikka whiskey for a client, Makro use Wumdrop to get it delivered but item was never delivered to client and online on Makro sight it says delivered. I specifically instructed the driver to call the client on delivery. Horrible experience, no communication from Wumdrop and I try to phone Makro but can’t get through. Poor service delivery, Makro please make sure the whiskey gets delivered pls.. it is not that complicated or get another courier company to use. Please contact me so we can get this sorted.
