Vodacom call Centre Bad Service

I'm really not happy with Vodacom service I have logged a query since May 2023 and the case has not been resolved until now they are still deducting until this date even though the investigation results are out and the consultant was wrong but they deduct because of their courier that is not fetching their router which I'm not even using. They said their turnaround time is 5 to 10 working days, now we are in the 3rd month. I really do not know what else to do at this moment cause I do not want to reverse and dent my credit score. I'm going to put this on public if Vodacom deducted this month again I'm really not happy.
