Mistakes made when account was setup

I opened a Premier Banking Account with FNB last week, and have been waiting for more details regarding setting up my account.

I have only received one email thus far, and decided to set up my online banking this morning. For some reason, my phone is not receiving SMS, so I wanted to receive my OTP via e-mail, but guess what... My email address is SPELT WRONG for where I should request an OTP... I phoned the online banking helpdesk, and then was advised that I need to go into a branch to resolve this... I have been with Investec Private Banking for the past 5 years, and have never had to go into a branch. Now just when I want to trial FNB, and somebody from FNB makes a mistake, now it is becoming my problem to have to go into a branch to resolve YOUR mistakes. I am really reconsidering whether I should actually proceed with this FNB account, as this is really not a very good entry for me as a new client.

Furthermore, I do I receive an email but then where I should request an OTP, it is misspelt?

Also, why is due care not taken by your employees to ensure the addresses are spelt incorrectly? I know my name is a bit unusual, but I ALWAYS take due care to ensure I spell names correct, especially when it is so crucial!

NOW I HAVE TO TAKE TIME OFF WORK OR SOMETHING TO GO AND RESOLVE YOUR MISTAKES AND I CAN NOT EASILY RESOLVE TO JUST MOVE OVER TO A NEW BANK!

AGAIN, CONSIDERING WHETHER I SHOULD ACTUALLY PROCEED WITH FNB OR SHOULD I JUST REMAIN WITH INVESTEC AS I HAVE BEEN THE PAST 5 YEARS AND RATHER CLOSE MY FNB ACCOUNT NOW
