Network constantly down, no service but you must keep paying

The rating should be Zero. I have been phoning for over a month because the Vodacom network is down constantly the whole day and night long, on and off. There is a repeating No Service message. I have asked that my contract can be terminated a month early as it is due to expire on the 21st of October. Not possible, Vodacom is not delivering their part of the contract ie a cell phone service but you, the customer, have no rights and must just keep paying. It is actually outrageous. The technical department has never called me no matter how many "customer service" representatives tell you that they will. They have a captive audience bound by Their Rules and Conditions and apparently you have no rights, just suck it up and pay. That is obviously the new business ethic in South Africa, no wonder so many people are emigrating. I asked Lance who called me just now, only because I've posted on Hello Peter, if I could at least get a rebate as the service is faulty, no he has no jurisdiction over that, so basically not.
