Is it so difficult to send an OTP across the sea?

I moved out of South Africa 12 months ago. So before i left i changed the OTP delivery method to e-mail, but here's the whammy. I receive my e-mail OTP for mobile banking but the OTP never arrives when using internet banking.

So i have tried unsuccessfully for 9 months to get Standard Bank to resolve this technical glitch of theirs, but to no avail. After this lengthy process I have asked Standard Bank to change my OTP e-mail address. After much toing and froing and me providing them with everything that they could possibly ask for, they have told me that the only way that they can add another e-mail address is if I present myself in person at a branch in South Africa. Can you believe it!?

This is a major problem for me and needs to be practically resolved.
