Vodacom is useless

I have tried to upgrade now for 3 days online. The site only wants to allow me to upgrade for double deals. Why would I want 2 phones?? There is no reason why I can't upgrade for another deal!! So I tried the chatbot - who kept asking me the same 3 questions over and over and over. How many times can I type my name? Then I asked for a call back. Oh please...incompetence at its best. I gave up. Now I will google how to cancel my contract. Vodacom is useless!!!!!
