Frustrated customer

Am so sick and tired with Telkom,I have a router contract with them since late last year and my subscription on it it R136 now recently they debuted meR2800.I then queried it and I was told they system shows there is a ********** account added onto my name they then advised me to go to Telkom store with Id to verify I identify which they didn’t do first when the second account was added well I did and there I was told to do an affidavit and I did that.Before I could submit affidavit they had debited be again 1800 on the same month luckily I would reverse those amounts.I asked the consultant that I cannot reverse maybe now since I have a case pending for investigation can they put cash payment on my account he then said they won’t be able to do it I should phone account department or something.I now have a case number but they are still continuing to debit this time was 1500 on Friday and R3800 on Saturday I mean this is causing so much inconvenience on my side,I phoned their *********** call centre for getting them to note my account as cash and update me on my case since no one there has ever called me after 8 to 10 days of submitting an affidavit and after the consultant advised their turn around time takes 7 working days but when I asked him why has no one contacted me already he couldn’t answer and changed his story that investigation doesn’t have turn around time,so for all I know it can take years to investigate department to attend to my query.Nevertheless I asked him to remove my bank details and note as cash Payment he told me they cannot until the investigation is complete they will have to keep on debiting,which for me doesn’t make sense as I customer i think i’ve got the right to have such requests,look am not saying I will stop paying my existing account what am saying I can go and pay it cash and until the ********** case is complete they cannot have access into my account.So what I can do now is keep on reversing these transactions I need this matter to be dealt with urgently and to Telkom to take its customers serious because what they doing now is giving me the impression that they now willing to resolve this as no one is that I call can give me clear answer or solution.I think I should escalate this to consumer regulations as well maybe I can get help and continue with my life.I cannot wait for my contract to expire I don’t want anything to do with Telkom and I won’t recommend to anyone it’s a **** company excuse my language am just frustrated.
