Useless Vodacom customer service

I have seriously had enough of Vodacom and their utter disregard for customer service. I have wanted to get an upgrade on my 2 daughters phones for Christmas only to find out that I apparently did an upgrade with Vodacom rewards in 2017. I have now got to wait 3-5 working days in order to get this sorted. This so called upgrade was so amazing that I received absolutely nothing for it. I cannot wait to change providers as this service is beyond shocking! What frustrates me even further is that we have been with them for years and on my account alone I have 3 phones and 2 ipads clearly they don't need my business.
