Metrofibre still has not sorted out billing problem

Logged my 1st complaint on 15/08/2024 in connection with wrong billing. Was told it was sorted.... YET the R175 is still as outstanding on the app. I phoned yesterday and was told credit note has not been loaded and they would phone me back..... I am still waiting. The debit order was returned twice already as amount was wrong. My bank charged me R100 each time..... Is. Metrofibre going to give that R200 back?? Today is 28/08/2024....I can BET that wrong amount will be debited aga8n from my account.... Will metrofibre give eme back that R100 when the debit order is returned? I am tired, no one can tell me what is going on.
