Dissatisfied with service

Good day

I sent a whatsapp request to change a debit account from fnb to standard bank on 22 February 2024.

An agent called Zolani S assisted with lining a new debit card on the system, today 01 March 2024, an amount of R399,00 was debited from the same fnb account which was supposed to be deactivated.

I was on a back and forth chat with Refilwe from 11:19 to 13:35, a very unproductive chat with a clueless agent who kept on asking me tedious questions on things that are on her system instead of resolving my query.

Can someone with more insight advice on why fnb account was debited instead of standard bank.

Refilled refused to provide me with the complaints email address hence I am using this platform, with her attitude and no empathy for clients I am shopping around for a more professional, efficient service provider
