Standard bank. Claims to assist in switching debits are false. who is fooling who?

On the 30.11. 2018 I was referred to std bank marble hall to open an account for my home loan.. I was assisted by a gentleman called Mahlatse Mcdonald Mello,I believed he did everything in his power to make sure that I went home satisfied. We open a new account and transfer all my debits to the current account but to my surprise yesterday 15.01.2019 no debit went off on the std bank account but on my previous bank account and I am k ow aware that most off my accounts bounce back because of this. Now I'll have to face a bad credit record for months because of your service consultant didn't do a thorough job or the system used is messed up...what a way to start my year. Thanks
