Migration not gone through even though im paying for it

<p>I've contacted Vodacom 10 times and no one can assist me with this. I have upgraded my phone around 20 April, and also at the same time upgraded my package from a Smart M to Smart L. I was told that the migration to the new package will go through on 1st of May. It is not the 13th and it still hasent gone through yet even though im being billed for it.</p> <p> </p> <p>I can also not do the sim swop to my new phone because the system errors out on "Migration pending"</p> <p> </p> <p>I need this resolved ASAP or at least just a solid answer why and that any billing must be reversed.</p>
