New contact but without promised deal!!

I just renewed my contract with Vodacom and notice the bundles agreed upon and price are different. The person who helped me with my upgrade and who took the time to help me with a good deal has not responded to my emails and the social media team have passed me off saying it’s not their department? Usually in the passed no matter what the issue the social media team assist be it account balances, data bundle queries, upgrades, problems with the app, notifications etc. But this time they are passing me off saying the person who I did the upgrade with needs to handle the issue. I am really so sick of having to complain about Vodacoms service! It is becoming tedious and beyond infuriating. I am concerned as the contract is supposed to reflect 2 gigs of data which is visible on the app but the 10 gigs of data are no where to be seen! I am well with in my rights to request cancellation of this new contact if what was offered to me first reflect on my new balances!! I emailed the person responsible and who assisted me with my new contact on Thursday already, Friday again and today and still have no response. The social media team claim it’s not their department?? I’m anxious and worried as the new contract has been activated as of the 30th of October but the data bundle promised is not there!! I accepted this contract based on that specific bundle & new handset!! Would the relevant persons please respond???
