Simple task cannot be done

Despite numerous requests to the branch to change my number and email address on my profile, I have been battling for close to a week to get this fixed andI it is still not done. How difficult can it be to change my details. I am so annoyed that staff of Standard Bank I spoke to, says its changed and its still not change. Then to top it all, the Calll Centre agent I spoke to, deactivate my internet profile and says I must register again. I have been battling for a week to register as my details is not correct on the system. Can someone please fix this!!!
