Impossible to get hold of / zero response

I have been trying to reach Standard Bank in South Africa from overseas. I have tried email and the international call center. No replies to emails are ever received. Phoning the international call center is hopeless. The selection options are not applicable and if you select an option you get sent to one of the other options that you never selected. If you get through to an option you wait with no response. The website is hopeless with dead ends everywhere. Really disappointed with Standard Bank.
