Nedbank card details ****** TWICE

I have been a customer of nedbank for 12 years. While my experience with the bank started off well, I has now crumbled with not even communication re the approval of a homeloan (of which the final decision was not communicated to me??), and my card details been ****** twice and my account cleared with online purchases on both times. How does one continue to trust this bank when not even the ***** department pics up that your card has been used in Doha or America and its unusual transactions? They tell me they will take 40 days to investigate what happened so now my access to funds is limited. Banks force you to have apps etc and then punish you when their systems are breached by taking more than a month to investigate whether you are guilty of misconduct. This is completly in contravention of the POPIA, CPA, BA and the constitution.
