Trying to change my bank account details for 3 months now.

I have been trying to change my banking details since the 22'nd of January this year which has been a nightmare and is still not rectified.

After numerous attempts I finally got a response that I need to accept my debicheck debit order message. The only problem is that it has been set to my old bank account that I am trying to move away from.

I notified yourselves in writing that the end of March debit order must go off my new bank account as it will not be able to go off against my old bank account. I got a response that my account will be debited to my new account but it still went off my old bank account.

I have since manually paid the amount via EFT with proof of payment sent from the bank but now I have an email saying that I am in arrears.

Please can somebody with competence take over this case and just update my banking details? Also I expect no negative reviews or missed payment notifications on my credit profile as I have worked very hard to get and maintain my profile over the years.

I really cant believe that it is this hard to update my banking details. It was easier from Telkom and they are the worst company to deal with
