Cell C cant do change of ownership anymore?

I took a contract with CellC 4th of April 2019, I wanted to use the number that I then used(on my fathers name) and they told me I should take the contract and just let my father come in with his ID and sign the change of ownership documents.

We have done that and its been over 3 months now, apparently the superiors have not communicated that the procedure has changed and now no one has authorization to do it.

I have been to Cell C menlyn 5 times and called them probably 40 times, they told me that my father need to be there, he came all the way from the Free state for this, had all the necessary documents with us, completed the security questions. Still not able to do the change of ownership. They said they have escalated this now to their helpdesk but after two weeks stil nothing, when I call them they say they have followed up but still waiting for feedback

I even have recordings on my phone where the consultant told me the above.

I cant believe I have moved from Vodacom, I'm very disappointed

Please assist me. Or can I cancel my contract?
