very disappointed with the service

Absa ***** department notify my regarding a suspicious transaction in my account on 26/02/2021. They block my card and advise me to re-open another to the branch of which i did. However the transition still went out of my account even though they assure me that the money wont be authorized. I was hoping a bank would assist me since the saw this suspicious transition on time but they fail. I am very unhappy with them .I thought ABSA is able to prevent issues like this one.i am very disappointed with ABSA
