Email address not being changed

I have requested that Standard Bank change my email address for all my accounts. I was assured that this had been done, but going to apply for u-rewards I find that my work email address is still being used. I will not go into the branch for the 3rd time because of Standard Bank's incompetence. If ALL my email address are not correct asap I will go viral about Standard Bank and will move to a bank that can perform easy tasks.<br> Email address should ready [Email Removed]
