Vodacom Does Not Know There Own Packages

So for some odd strange reason Vodacom decided to remove Voice Bundles from my account and 3 other lines i have with them as well. Each time i log a ticket i get the same ****py reply stating i cannot buy Voice Bundles. I have been doing this for over an year and my package allows this with Airtime conversion to Voice Bundles. I am fed up of the ****py service from Vodacom and no one bothering to solve this. Again today I am fighting with support to get this fixed. Either Vodacom fixes this or changes my package free of charge,
