De*****ed for the 2 time in 2 months. TFG is a SCAAM

Writing for the second time and I bet I won't be getting any response again. In February there's was a *****ulent activity in my card. The issue was resolved on the 17 of May and no explanation was given. Thankfully it was in my favour and my account was credited.

A week later, the same thing happens. How is this possible if it is not an inside job? I unblocked and a got a new card, on 21 May, and today morning 29 May there's an "unsual purchase" (so they call it) that happened in KZN and I'm in Centurion. Now I have to go through experience with no stringent measures in place... TFG WHAT MUST HAPPEN?
