Refusal of cancellation

I called Vodacom on 07/11/25 at 10:23 to request for cancellation for my home wifi as I was aware that at end of contract the discount will fall away, there retentions agent offered me an upgrade however there was never a package delivery nor an update advising that I was declined. I did a follow up on 28/01/26 at 11:37 requesting for cancellation and I stated clearly that I did not want to be charged out of discount which was from R 306.47 to R676.99 and the agent said the discount will not fall away, she offered an upgrade from 100mbps to 200mbps. I advised her I doubt it would be approved as I am currently on debt review however, she insisted and advised she will downgrade my voice contract to match my score. Come February I received an invoice with no delivery of the new package and GUESS what the discount was not there I was charged full price. I did a follow up on 07/02/26 at 08:27 and AGAIN they force to retain and not focus the actual request. Feedback was provided after service request was logged ***, the call got cut off and she never called back. I called again on 13/02/26 at 11:06 stayed on the call for almost 37min requesting for cancellation and escalation of the issue. I was not called back till I called today 18/02/26 at 12:52 to be told there was service request raised on the 13/02/26. I want the data line cancelled and account charge removed.
