Worst experience with vodacom

After paying a premature cancelation fee to get out of my vodacom contract Vodacom still does not want to release my number to be ported to a new network. Not one call centre asistant can help me. Each person has a different story. This has been an ongoing story for almost 2 week. This is the worst experience i have ever had. Vodacom's call centre is totally unequipt to deal with any query.
