Cancellation issues with Vodacom

I began calling Vodacom giving notice of cancellation of contract on the 13 &14 Jan 2025, since it was reaching 2 years in a Feb. I had a data and separate minutes contract ending between 9-14 Feb 2025. I was offered many alternatives and upgrades but insisted i wanted to terminate. The was an unsuccessful debit Dec 2024, which I paid but was not showing on their side which delayed the initial notice, so I called again 31 Jan 2025. By end Feb the data contract was cancelled, and they upgraded me on my main number which I did not notice until later because on the call I made to ask if mid-month the airtime stop but was advised it will last till end of Feb. I called 1 March after noticing that it was an upgrade and an SMS for the upgrade actually said R459, but they have been deducting over R800 since March. I have been calling insisting on a cancellation and that i never asked nor agreed to a new contract as i wanted to compare as I was waiting on the new Iphone to compare best deal after March. I always take a phone with a new contract. These are the dates i called with different people not finding the previous resolutions Jan 13,14,16, March 1,3,22 On this 22 I physically visited PE Bridge shop and was assisted by consultant to call for the cancellation I referred to a case number 5 - ***6409 on my last call, I received a computer verbal confirmation and sms end date of 16 Mar 2025 also stating I must notice for end. The consultant was not seeing the end date of 16 March and the cancellation and told me I needed to cancel again which means it will be prepaid end of April 2025. She further logged a query over contract date of Dec 2024 to 16 March 2025 as she says they appearing as possible penalty for early cancellation for me and I was to receive an outcome response in 3 working days. I did not get it or missed it as that should have been Wednesday 26 March. Today 5 Apr 2025, I called to check status of cancellation was told they don't see it nor the last query and it is recommended I migrate to a R28 rands WhatsApp month to month and then cancel after May or she will log for notice for end of May 2025. I said all my calls were of cancellation since Jan they should log a query or case and use my recordings, I will do no more. Why should I trust, this one will be seen or acknowledged now. I have been with the network most of the over 20 years of having a phone briefly migrated to Telkom 4 yrs and came back. Their processes are unfair I cannot be doing endless notices whilst they deduct my money and not getting a service I needed, and I am paying double for very little data (and no device) that I knew I will have to get more on a new contract. I just want what I asked for on the at least 10 calls made since 14 Jan this year till today, the CANCELLATION of overdue contract no penalties and added months please. I should not be punished for an upgrade I never requested.
