Breach of contract

A Vodacom agent called me in September 2022 offering an upgrade on my data line. I accepted and all the formalities were completed. The new contract was suppose to be uploaded 01 October 2022. This was not done and during October another agent called me offering me an even better upgrade effective 01 November 2022, which again I accepted. Since then it was comedy of errors with the result that this contract also was not loaded. When I followed up today on facebook their team completely lost the plot. They informed me that my upgrade must be redone and that I must look on thier website and choose a new deal. This is insane!! I requested to speak Reuben, who assisted me previously. They ignored those requests. I requested for the contact details of a manager to escalate my complaint to. They ignore those requests and refuse to provide me with any details. I requested that someone from management call me to explain what is going on. They ignored this request and did not respond to this request. I do have a valid contract with Vodacom. I need to understand what is going on because from my understanding Vodacom is now in breach of contract. I would strongly advice that you assign someone from management to investigate this case as a matter of urgency. I am afraid if nothing comes of this I reporting Vodacam to ICASA.
