Unresolved Upgrade Query

I am very suprised that Vodacom concluded that the query has been resolved based on the feedback provided by me. Yes i did got a call from Vodacom on the 2nd Aug 23 regarding the issue i had and i am not happy according to the way it was handled as i have requested the recordings where i have agreed to upgrade the contract to my 073 number ending with 5963 but the consultant who gave me a call advised me that this is working in my favour which i believe it is because on the recordings they listern to there's nowhere i agreed to an upgrade but the sales person decided to offer me an upgrade which i believe to be *****ulant.

I was also told that a refund will be issued for the months i've been on a false upgrade and it was confirmed that this will happen within 7 working days but to date i have not received my refund but i am getting messages from Vodacom saying "Your next Vodacom debit order (R647.00) is on 2023/08/28." What is this debit order for because i cancelled my contracts with Vodacom? My contract ended in September 2022 and i did not upgrade to anything and will appreciate if this can be resolved A.S.A.P
