More than 48 hours just to reset a banking app profile

I've been banking with FNB for the past 6-7 years and was happy. Last week my banking app kept on denying my face ID and then I resolved to putting the password which I know by heart but still was told it's incorrect. After 3rd attempt my profile was blocked and I tried to reset my password which I did successfully but when I logged in again it went straight to tell me that my profile is blocked. I went to the bank on the 4th of May and they told me I should wait 48hours (which is new to me, since when do we wait this long to reset a password). I waited 48 hours since my last attempt and reset my password successfully but when I tried to login it gave me the same error that my profile is blocked. I contacted FNB and was told I need to wait 24-48 WORKING HOURS for them to get back to me. Which is ridiculous because I need the app to make a living. Why can't this matter be resolved ASAP if I can verify myself. Whenever I speak to someone I just get a "we are going to escalate the matter"
