Contract cancellation not actioned , continued billing instead of providing settlement letter mxm

I requested for a cancellation quote on 16th Feb 2025 and submitted a contract cancellation on 17 February 2025 and by then the February invoice was already billed and paid through the credit I had in my account , I paid the balance on VodaApp to cover the settlement quote and submitted the documents on 17 February 2025.

From around 20th and 21st I contacted Vodacom to advise of the cancellation status but I was taken from pillar to post being told that the status says in progress , I contacted Vodacom for a couple of days without any help

Today is the 6th March 2025 and I am getting a statement and invoice instead of settlement letter

I am so irritated right now because I did everything I was told and submitted the cancellation quote a day after the request but my contract is not cancelled , why ? May you please reverse the March 2025 invoice and close the account nxn please
