Shocking service from upgrades departement

I have made close to 10 calls this month to follow up on the non allocation of my data bundle to my new contract, which seems no one is able to sort out. Every consultant tells me the same thing...my team leader will sort it out before the end of the day. Seems leadership is lacking. This is after multiple phone calls on my previous contract that ended and Vodacom decided themselves to upgrade/increase my monthly fee.
