Vodacom exploiting senior citizens part 2

So on the 4th of February 2021, I lodged a complaint on hellopeter on how vodacom is exploiting senior citizens who are on pension, my dad in this case. He called them to lower his monthly installment since he was struggling to keep up. He was promised that he would only pay R680 monthly by an agent and he is now instead of paying R680 monthly, paying way more than what he used to pay.

A agent followed-up and called me on the 11th of February going through all my dad's contracts and promised me that she would email me the list and come back to me, so that we can resolve the issue.

To date, nobody has come back to me. It has been 6 days since I last spoke to an agent. And nothing has changed after my first post, 13 days ago.
