No service from Standard Bank S.A

I cannot complain about Standard Bank service because there is no service!! I want my EAP limit increased above R500,000.00 and no Standard Bank employee can or wants to help. I am in New Zealand currently and obviously cannot get to the bank. I am told to email this person then phone that person. Time difference makes it impossible and the amount of money I have spend to get hold of someone in Standard Bank is ridiculous.
