Rain leaches

From the date of November last year until January this year I have had some to no network on rain 5G I phoned multiple times, they've all told me the same thing to remove and reinsert the power and see if it comes right remove the SIM card I know the whole story because I run in IT management so I know the stuff and it seems to be a network tower issue but that didn't bother the only thing they bothered about is sucking the money from me now I have noticed in this month they have tried multiple times to debit for my account which I do not have money from and have not authorised them to debit on dates that they are debiting and it's costing R8.50 each time and they've tried to debit on multiple days in a row five six days in a row which I have not permitted them to do and I've contacted them and spoke to a representative who says I can do what i want which I don't understand what it means, they are debiting on dates on my account that I have not permitted and I want answers for this.
