FNB ****-taking customers for fools

I have been banking with FNB for over 20years now, since I was a student. How they treat their customers is disgusting. In 2022 April I received an sms, with an OTP number to authenticate an online banking login. I called the FNB ***** department to report. They blocked my banking profile and canceled my cards as a safety precaution. I then went to to branch to reactivate the profile. Then I was told that they will investigate and give feedback. That never happened. This year, 18 April 2023, same thing happens. I followed the same process. So I asked the person ( Kabelo) why I did not get a report back regarding my 2022 case, he told me that someone tried to call me and then sent an sms. Guess what, the ***** department don't even try to call, they just fkn sent the sms "FNB :-)Good day Kindly note that I tried calling to no avail . Please call Carren Mokoena on *** regarding the ***** case 2023-****". How do I get comfort that they are actually taking the cases we log seriously if they don't even have the decency to call their customer? I am annoyed, and in the process of changing banks.
