Livid customer

Got a new contract deal with Vodacom last week, everything went well until they referred my order to be delivered by SkyNet. And they have not bothered to send any communication regarding the arrival of my order, no one ever answers the phone, tracking on WatsApp gives old information. The reason I have a problem with Vodacom is that when I called them to complain and seek some sort of resolution as to when my order will be delivered, they admit that they know they have had many complaints regarding SkyNet yet they continue to use them which then makes me feel like they have no regard for their customer because why would a company subject its customers to such incompetence.
