Vodacom shocking service

I eventually called their call center to convert my contract to a pay as you go after requesting for the last 6 months that this contract be converted to a pay as you go. The agent I spoke to did not understand the basics of what I was trying to achieve. It sounded like they were more interested in continuing the party they had going in the background. I informed her that I have spent the last six months trying to get this contract converted but she informed me that there would still be a 30 day cancelation period even if the contract had already expired some two years prior. Is this how Vodacom make their millions?
