Standard bank not protecting customers against *****

On 16 december 2021 i received email from standard bank to my registered email address which i gave to standard bank when i opened my account ,stating that i have not claimed my ucount rewards and i need to sign in to claim it ,so i signed in to the link went onto standard bank banking app ,all showing standard bank app ,so i signed in as i normally do with my email address and password ,then on the standard bank website it ask that i must put my otp to sign into my account ,nothing looked ********** because thats how i normally go in ,and within a minute 4 transactions went off my account saying i paid my beneficary but the banking details are not the details saved on my account and normally i would get sms saying i am about to make payment but nothing like that came through ,FNB send you notification on the app to make payment but nothing came through from standard bank about these money being ****** from my account NOW I LOST R7634.00 TO ONLINE ***** AND STANDARD BANK NOT TAKING ANY RESPONSIBILITY FOR NOT BETTER PROTECTING ITS CUSTOMERS
