There is no service at Vodacom

I have been trying to early-cancel my contract and convert to pre-paid for nearly 5 months now. Whenever I go to a store, the system is not working.<br> <br> Whenever I phone ***, the consultant passes me on to the call centre again.<br> <br> I would like to make a formal complaint about a call centre agent, called Mpho, who took my call today, was incredibly rude, put me on hold for more than an hour (obviously so that I could not rate him), and then cut me off. This service is why I want to cancel my contract.<br>
