Vodacom refusing to close my account after paying the settlement amount

On the 13th of February 2024 I requested a settlement amount so I can settle the amount, and I was sent a form with the total amount of R4349.38 and was told that it is valid for 16 days (also written on the form), then on the 26th of February 2024 vodacom took their monthly premium of R349.98 and the following day which was the 27th of February 2024 I paid the settlement amount (14 days later) of R4390 and sent the form to cancelations the following day on the 28th of February 2024 and chose to keep my number as prepaid and I received an sms on the 1st of March 2024 explaining that my number has been converted to prepaid but never received any sms/email stating that my account has been settled, when I call the call center people tells me that there's a balance of R376 that I still need to pay for the data I received for March and I never received that data, I called my bank to stop vodacom debit order because I don't owe them anything, vodacom is nonsense and wouldn't advise anyone to do business with them.
