Vodacom not sticking to promises of replacement phone

I have been stringed along by Vodacom since last year September about the Huwai phone that I was upgraded to. Eventually I was contacted and the phone collected by RAM in December, with a promise that I will get a phone call to reverse this upgrade to a more suitable phone in January 2021. I have tried to upgrade however my records still show that I have the phone that was collected and that I cannot upgrade until June 2023. No one really listens or gives a damn and I pay +- R3k a month for my packages and I dont have a decent operating phone. I tried to upgrade to the latest Samsung as you could get a reduced rate and earphones. Couldnt do that . Where do I go to and van I get the number of the CEO of Vodacom or should I put up a bill board or can the consumer Council or Carte Blanche help. Look at all the websites dealing with Vodacom's Services,Service rated - 10. I am a business owner and ned to operate my business fro certain Apps which I am unable to do
