Worst service at Standard Bank

I'm currently working abroad and need to receive my OTP via Email. I've sent multiple emails to information@standard bank.co.za , I've called their International Online banking line, (+***1) - as requested on the phone, I've sent all the required documents to finalise my request of changing my OTP. Every time I just receive the same "automatic " reply. No one is assisting me, every email states that this can you only be done over a phonecall, which I have made. You've only cost me money and still I've had no success with you! Worst service.
