Vodacom takes 2 hours to assist

I have started calling at 13:23 today to make a change to my delivery instructions on an upgrade. Have spoken to numerous consultants only to be put through to the next consultant who is apparently going to assist me. I then either get cut off and have to call again and then even get asked to rate the level of service I've received. What service? It is now 15:07 and I'm still holding to be assisted. Of all the industries during this time, this is the one industry who has more than enough money to appoint more consultants in their call centres, so one doesn't have to hold for 2 hours before being helped or probably longer, still waiting to speak to someone who can help.
