How Long must one wait and still pay

Took out new contract on 16.05.2015. Even though the 1st installment was already deducted a week ago this contract is still not working, so I am paying for something I cannot use and Vodacom cannot provide me with answer. Everytime they just call and say that are busy with it.<br> <br> Problems in short:<br> Waited 3 days before sim was active (only after sim swap) - FYI - New Sim!!<br> Could only receive calls for 3 days after this, couldn't view balances or make calls
