Vodacom - Customer Service sucks

I am so frustrated with Vodacom and their answering system. I am due an upgrade and have now been trying for a week to order a new phone via phone and also on-line. Automated system tells me I* am not due an up-grade - which is a lie. On-line ordering tells me I have to take a 36 month contract - no I do not have to. Nothing works so eventually I pushed the "Cancel Contract" button to see if I get any response. No wonder people are getting fed up with Vodacom I just want to talk to a person not a machine.
