Bad service

I'm not happy with vodacom service, firstly, I bought 1month black friday special 30gig nd vodacom made that recurring without consulting me, I called on the 21st January 2020 to cancel this service and asked them why they made this recurring without consulting with me, the consultant said she will log a call, while waiting for the feedback I received a message that the call was closed, they asked me to rate a service nd I did and also explained that I'm not happy that my query was closed without them consulting me again, still they didn't call me or do anything about that, secondly I called them on the 1st February and asked them why they allocated this again, the consultant was rude to an extend of telling me I don't understand myself when I asked him to put me through to her supervisor, I will like to report this to their executive management
