STANDARD BANK INCOMPETENCE YET AGAIN

After 5 attempts to get my OTP number sent via my email, I'm finally told that this has been done. What Standard Failed to do was update my account. My old number is no longer valid and I can Not get into my own account to verify as they have not added my new cell number. WHY ARE YOU SO *********** and UNPROFESSIONAL that a simple change of data seems to be way above the capabilities of your staff. CAN SOMEONE PLEASE RECTIFY YOUR ERROR.
