Flawed security questionare system @ FNB

How is it that my back for more than 15 years ask me auto generated security questions that is incorrect and I answer based on the details of the questionare and I fail the test, then during this time of COVID the agent is not allowed to assist me due to my failure of answering the questions the way I should I have to go in a branch to get assisted, I think its time to consider a move. So dissappointed
