Mfc nedbank compromising private information sending it wrong emails

For such a huge bank to drag peoples credit scores so low, MCF had my wrinf details captured on their side after I have called everytime requesting my car installment and they claimed to sent them everytime, my worry is that my private safety have been compromised since my emails were sent to somewhere not in my emails thanx to their consultants who captured wrong information, due to Popi act I have take this to the court of law, my privacy was compromised and on top of that they claiming that my account is in arrears due to the debit oder link that was sent to update my account and I've been telling them that I received no link since my email was captured wrong today I'm in arrears because of their fault
