No Voice Mail Box

<p>I purchased a Smart XL contract and for several months now are unable to set up a voice mailbox. Every time I dial 121, I get an option to set up the voice mailbox by selecting option 1. As soon as I press 1, the call ends. The call centre has been unable to help to date. After the last call, I gave up and have now attempted this forum to see if someone at vodacom is able to help get this right. I hope someone will contact me with a solution. I just need to get this set up and don't seem to have access to someone who can assist effectively. </p>
