Vodacom is trash 🤬

I called last year july requesting settlement letters for early cancellation, one of their agent sent me all three of my settlements and advised me to send proof of payments of which I did, debits were canceled since then. Fast forward to march this year 2023 Vodacom debits my account, I then called to find out why as I have “settled my accounts” , I advised that they will investigate and give me feedback. Next thing I get an email from MBD that Vodacom handed me over to them, HOW? While I’m still waiting for feedback from their, while I believe I have settled my accounts I even have the proof of payments and early cancellation settlement letters?????🤬
