Vodacom's TRANSFER of data = charged full amount to your account

I still have a unsolved dispute at Vodacom. Reference number: 1- ********** **********

I’ve done a TRANFER of my data to another phone. I’m the account holder of both the phone numbers. Vodacom CHARGED me full price on the data TRANSFER. They confirmed the fault and correct one of their charged 'faults'. They promised to compensate me, but ignore me since. My concern is for all Vodacom customers! On my account they stole more than R200.00 from me. If they do this to each and every client how much do they pocket? I tried to resolve this without going to the media. I’ve already contacted Carte Blanche as well to report this. I hereby request an urgent investigation at Vodacom, it seems they do not understand the difference between transfer and charge!
