Vodacom customer service is a joke!

I just had the worst customer service with Vodacom I've ever had. Trying to upgrade your contract with them is an absolute nightmare. Their staff are totally ***********. Instead of upgrading my contract they created a new contract with a new number for me. After two weeks of battling, I still have not been able to upgrade my contract or get a new phone. Upgrading online seems the easiest option as they never have any stock at the Vodashops, also upgrading online says next day delivery, now they say 3 to 5 working days? I am currently waiting almost 24 hours and counting for someone to call me back to confirm my order. It's a absolute disgrace! I've been a client of Vodacom for 20 years now and seriously considering changing service providers.
