Vodacom personnel don't know how to cancel contracts

How hard is it to just press a few buttons on a computer and cancel a contract? I've wasted almost an hour of my day trying to cancel a contract, and all I hear is but we have this or that option and and and.... seems like they don't know about the consumer protection act. This is close to harrassment. I just want to cancel a contract, that's all. If no one can help me with something that simple then I would rather change to another service provider.
