Told as loyal Client get more data reduce cost just to be surprised with a bill almost R500 more PER MONTH!!!

I was called to say i will get extra data on 2 of my contracts but my bill will decrease byR200 now my bill increased with R500 from previous month because instead of just adding extra data i am now also on 200 min per contract which i did not agree to or told would change this needs to be fixed - listen to my recording from the conversation and fix the contract and refund me please this is not what was promised. Not cool at all
