Wesbank holds Covid lockdown payment failures against your credit record

I had non Payments on my vehicle straight after the lockdown started. I corrected it and made a huge effort to keep my account up to date until now. Now I cannot get any further finance due to the fact that Wesbank registered my non payments on my credit report. Ive been trying for days to get a manager or supervisor to speak to me so that we can resolve this...there must be some merit in the fact that the lockdown was forced on us and that I managed my account very well before and after lockdown. I keep getting aitomated responses and generic answers, but even after requesting it numerous times, a person of autority fails to communicate with me.
