Vodacom refund still unresolved after months

Vodacom’s service has been shocking and completely unacceptable. I was told that if I wanted to keep my father’s cellphone number active, I had to pay up the account. I followed Vodacom’s instructions and paid R94,588.61 from my own bank account, only for Vodacom to then delete the number anyway. How can a customer be told to pay in order to keep a number, do exactly what was asked, and still lose the number? On top of that, I was later told there is a credit of R28,651.64 due back to me, but this refund has still not been finalized. This is poor service, poor communication, and a complete lack of accountability during an already sensitive family matter.
