Still no reply from Vodacom

I'm very disappointed, and frustrated. Nobody is getting back to me, and my account is a mess because of unauthorised changes that was made to my account without my approval. I also battle with slow internet, as I can hardly get 5 to 6mbps on the internet. I have signed up for 5G Internet, and this is no longer in the area, and I'm not even sure what is now in the area because the internet is soo slow. I think to rather cancel this because I have signed up for 5G and Vodacom can no longer provide this, and I'm stuck with a very slow connection with videos constantly buffering. I also need a reference for this complaint, because if you can't get this sorted out, I will refer this to ICASA and the Consumer Protection Council.
