Vodacom false and misleading advertising.

I added a "Red Hot Deal" from the Vodacom SA website using their App. The deals on offer included 500 minutes @ R33-00 or alternatively 250 minutes @R18-00 recurring every 30 days. This deal sounded unbelievable and incredible. When I checked my account this morning I was billed for almost 10X the advertised amount. This is false advertising and very misleading and tantamount to *****. I have called Vodacom and emailed them to have this matter addressed as a matter of urgency. I even attached a screenshot of the deals on offer and desire them to honour their advertised deals and to reverse the incorrect amount being deducted and added to my upcoming bill.
