Sim not provisioned

<p>Moved to Vodacom 3 weeks ago from MTN. Could not use my new phone for the majority of the time as the sim card cannot connect to the network. Had to pay for another sim which also didn't work, only to get a third which still doesn't work. No help at all in resolving the issue and cannot get an answer from either the call centre or store. This has been a terrible customer experience!!! No one can fix what seems to be a simple problem, yet i have to pay my bills for a phone i cannot use? </p>
