Incompetence - who can update my residential address on my statements????

On Friday 29 December I visited FNB at the Mall of Africa to update my residential address which is also my new postal address. The person helping said that my profile had been updated however he was unable to update the address on my personal loan and home loan statements. I was advised to call these departments and request them to update the statements.

1) Home loans dept - the account is a joint account and because I was unable to provide my husband's accounts details (the account being debited) they refused to help me and directed me to either the branch or telephone banking. The branch couldn't help me last week so I doubt that's changed and I'm not registered for telephone banking!

2) Personal loans dept - I was on hold for 37 mins and spoke to 3 different people. The last person I spoke to said that my she did not have a mechanism to update the address on my statement and that my statement would automatically be updated with the new residential address on my profile. This is not what the branch had told me.

Surely clients need to update their profile once and not with every department that they deal with in the bank? Am I being treated poorly because I do not have a current account with FNB? Surely this is not the way to attract new business??? What do I do now? Who can give me the correct info and send me updated statements with the correct information? I am NOT going back into a branch to waste my time again.
