Paying while no service

Firstly, after adding an additional SIM card to an existing contract I was not told of the additional charges, even after asking. But ok, my fault I should have read the small print. So at the same cost of just a sim I can get an additional contract with 2gig data. So I sign up. It's been two weeks and still awaiting the connection. But no doubt I'll be paying from the date I signed up even though I have no data. I'm now waiting 26min for the call centre to answer the call to get this resolved. How in the hell do I get hold of them for them to do nothing more than what I am paying for. Another pathetic corporate. Why do we need to deal with incompetence like this in SA. It's unbelievable.
