Bad customer experience on Vodacom contract

Took out a contract with Vodacom. Only after 2 weeks my order was sent to the courier. I get an sms saying my order is out for delivery. 3 working days later I still haven't received my order that obviously not counting the weekend. We are referred to ordering online with a promise of getting your things withing 72hours but that not the case. Responses are all robot type responses and then told to follow-up with the Couriers when my deal is with Vodacom. Everyday I'm told that I will get my delivery today and the day ends without anything happening. Customer service means you have to call the customer and make sure they are happy and have receive their goods in order but I have to constantly call and follow up to get any kind of response.
