No response from IT division on blocked App

<p>A month ago i was out of the country and unreachable by standard bank. While i was abroad my banking app and card was stopped because they thought the transactions on my card were *****ulant. After returning to South Africa i was told that i had to get a new card and card number to rectify the situation. 2 Weeks now after receiving my card i still cannot access my banking app. When i try, it throws out a message reading" ACTION BLOCKED This action may compromise your banking security. For your protection we've blocked this action and prevented further access." I have contacted Standard bank multiple time to rectify this issue, only to be told every time that they will raise a report with IT and i will be contacted shortly. Its been a month still no calls from the IT devision. I NEED TO RESOLVE THIS ISSUE!! Please contact me!</p>
