Epic Vodacom fail

I paid up my data account with Vodacom on the 29th of September 2021, after calling them on the same day to get the amount required to pay it up(settle it). I was told that I could call back after a few days in order to cancel it when the payment reflects as I no longer want this account. Upon following up with Vodacom today the 13th of October, the following transpired:

1. Spoke to Precious at Cancelations at 11:26, who informed me that the payment from 29 September didn't reflect and that my account was now in pre-legal awaiting handover. She then told me to speak to Billing/Collections department in order for them to allocate the payment.

2. I call Collections immediately after speaking to Precious and spoke to a lady called Ntokozo who told me that she can see that payment was made and that she would update it for all departments to see and that I should call back Cancelations department at around 13:00 as the payment will take up to 2hrs to reflect.

3. I call back Cancelations at about 15:43 and speak to a gentleman called Gavin. Gavin denies what Ntokozo said about the 2hrs and says it actually takes 12 - 48hrs for payment to reflect, so I need to call back again after that time delay has lapsed. First he said I can't cancel the contract prior to it lapsing, which it has, in June already. Last I checked one pays a penalty if it's a case of cancelatiion of the contract before it lapses. He also said that the contract goes on month to month after it has lapsed and it has not been canceled and I get billed for that. How do I get billed for a service I did not receive. I can't remember when last Vodacom allocated data to me, which I do not want by the way. Mind you this is a payment that was made about 15days ago and its negatively affecting my credit scoring, but still no proper allocation of it by Vodacom.

I want this issue resolved and my contract canceled so that I can go back to using my number on prepaid. I want nothing to do with Vodacom anymore. You have failed dismally as a service provider. I actually trusted you guys, but your service is appalling to say the least.
