Paying for telkoms mistakes

In January, I went into telkom Westwood in Durban to open another telkom contract, I asked for my debit order information to be updated as the exiting account was being debited off my old bank account, the consultant told me she has updated it and it will be fine, still my old account was being debited n I got charged R204 rejection fees, which I paid the first month as the consultant said it will be updated the following month, I then got charged another R202 rejection fee, the consultant has not done what I told her and the information was not updated, I am being charged for her mistake, I called telkom and they said they can't do anything about that charges I have to pay it or my account will be suspended.
