UN AUTHORISED DEBIT ORDER

I am disgusted by the service i am receiving for money that belongs to me . I have no business with telkom but they have been deducting money from my bank account since april i queried it and had to do several reversals from my bank which affects my credit profile cause of unpaid d/o i have sent in documents to proof that i have no relationship with them no one has contacted me . A stupid consultant updated the customers banking details and input the wrong account number now its taking my money every month this ia focken ridiculous i am not getting anywhere with telkom the manager said someone will call me took down my details and still nothing i dont get this if a customers d/o bounces they must confirm the acc number again but they dont they keep on arranging a d/o from my account this is pathetic i will never recommend them and i wont do business with them ever im glad im not a customer i will never be too ...i mean what if that was my last money taking big amounts at once is pathetic . To make it worse since debi check is in place i nevrr got a authorisation from my bqnk either so what is telkom busy with doing UNAUTHORIZED DEBIT ORDERS WITHOUT MY CONSENT!!!!
