Vodacom Sim Card disconnected

<p>I've been having trouble with my vodacom sim card for more than two weeks and none of the different departments at vodacom helped me. They're always showing me to a different department and than that department tells me they going to log a call and i stil cant use my sim card at all. i called their head office where that lady told me they going to call me back and i stil heard nothing. My vodacom contract is up to date and i still cant use the sim card. The sim card not working is getting me into trouble at work because i'm an IT Tech and when they cant get hold of me they getting angry. Can you guys please help me because vodacom seems to be ignoring me.</p> <p> </p> <p>Thank you</p>
