Vodacom rewardsco

Ive been a long time customer of vodacom and the relationship has been good until i was due for an upgrade in 2021. Fast forward 2023 when i was due for another upgrade i was told that my previous upgrade was for 36 months and this happened without my knowledge. I followed up on the matter and till date iam still waiting for the recordings of thag upgrade. Now on the 2nd of january i called becsuse i had not recieved my monthly data. I called and i was told that that was only for 24months and the rest of the 12 months iam to pay without those benefits. How i asked? I was not informed of the 36months contract and furtther more i was not told that id only get data for 24months.

Now vodacom call centre assistants are refusing to give me the name of the guy who initially did my contract and the recordings of that date. Iam being send from pillar to post and not getting the help i require. Vodacom wants to continue taking my money yet i did not agree to any of these things and they are clearly not willing to help.
