Vodacom Skynet partnership

I have never been so frustrated and disappointed by your service and your courier partner Skynet is making the entire customer experience hell. Skynet, Vodacom's courier partner has been promising to deliver my device yet to date the delivery has not occurred. They allegedly arrived at my workplace at 16:50. There is no communication from them. When I try to call them to schedule the delivery for during the day, as my workplace closes at 16:00, only to realise I'm caller number 40 on the line. Their WhatsApp line is none existent. This is not the service I've come to expect from Vodacom. And I'm on the verge of canceling the entire contract.
