Vodacom get your act together!

I changed my banking details for my Vodacom fibre in November 2022 (I have the reference number to confirm). I was told that this process takes a while and that it would be better if I make an immediate payment to avoid being suspended, to which I did. Yesterday 2/02/2023 I was called and informed that my account is in arrears and that I need to make he payment of the 2 months outstand (I did not take note of the deductions for the last 2 months as I assumed all is in order. VODACOM CONTACT CENTRE DID NOT GIVE MY NEW BANKING DETAILS TO THE BILLING DEPARTMENT. Yesterday I agreed that they deduct it immediately and today they still say its in the process!!!! How hard can this be?!?!?!? Wont this then affect my credit rating. I am BEYOND FURIOUS!!!!
