Unhappy client

I changed banks from Capitec to FNB, I was then informed by the bank that they have transferred all my debit orders. To my suprise when clientele called I had skipped two payments.I then gave them my new account number. I called them to assist me with my Divorce and I was told they can't help because I missed 2 payments. I have been their loyal clients from 2016 and have never missed payment and this is how I am treated. If they don't help me I'm canceling my membership and going to legal wise. Tomorrow I have to go to the magistrate court and stand in those long queues while I have lawyers that I am paying monthly.
