Nedbank's *********** Service has me regretting ever banking with them

I am so disappointed and dissatisfied with Nedbank's services, to the extent that I regret not leaving the bank sooner. Just over a year ago, my account, including my credit card, had unauthorised transactions resulting in financial losses (just <9K). Despite reporting this issue to the bank and multiple follow-ups, the issue case was never resolved, I actually grew tired of running around. Last month I finally decided to start my migration from the bank, I decided to close my credit card. The process is again proving to be hell! Upon visiting the branch, I was directed to the call centre. After painstakingly navigating through the account closure procedure with a representative (presumably a customer retention specialist), I was assured that my account was closed. I was even told to discard my cards. However, it’s been almost a month since that conversation, and I haven't received the promised confirmation email. Instead, I've noticed that Nedbank debited bank charges to my supposedly closed account, leaving me concerned about potential additional payments. The lack of care, professionalism, and basic respect for customers exhibited by the bank is deeply disappointing. I am left wondering about the timeline for the official closure of my account and who is responsible for the accruing bank charges during this unresolved period. After being a customer for over 15 years, I am disheartened by the quality of service provided by Nedbank.
