Repeated *****ulent transactions

After almost a decade of a largely pleasant experience Investec has lost all security credibility. A month ago, I woke up to 20 attempts and 7 of those R89.99 attempts went through of *****ulent transactions. The communication was less than desirable and after follow ups that money was credited bank to my account. I collected a new physical card from their branch. Less than a month into having this physical card, having used it to tap ONCE at Clicks, not added to ANYTHING and stored away in a safe at home where I live alone and only using the virtual card on my phone. But, this brand new physical card has had 4 *****ulent transactions of over R23 000.00. No SMS notification. No 2FA requests and the way forward is that I should collect another physical card and yet another ‘investigation’ that might take up to 10 working days will ensue !! What is the point of getting another physical card?? Is it sensible to continue to bank with Investec?? Should I wait until my entire salary is wiped out?? I still don’t know what occurred in the first *****ulent transactions case yet here I am!! You can no longer claim the secure bank trope!! Based on particularly these latter events, how am I meant to reach any other conclusion except that you gave me a replacement card that was already compromised?? Fix your security issues and communicate better !!
