Lack of action on previous complaints

Absolutely horrible feedback on my previous complaint. They didn't do what I originally asked after they put me in a position for wesbank to take over by not giving feedback for over a month on my covid 19 application for credit card and vehicle on wesbank side. WesBank had to take over, now fnb are insisting I combine the 2 or nothing and won't draw up an agreement for just the credit card, instead insisting I sign for both, and saying I won't get charged for both only the one, which is ridiculous considering if I do that, they can take all types of legal action when my car is already covered by another party and in my opinion completely bullying based on the information that I have given them on how I've been affected by the effect from the lockdown
