After 4 months details have still not been changed

In January i went in to the Standard Bank and The Grove shopping mall to change my address. After queuing for over an hour i was finally served and told it would take one month before the changes would be in effect. A month later the address hadn't changed so i went to the Menlyn Shopping centre branch to find out why it hadn't changed and was told that the request had only been put through for one account but that she would send the request for all my accounts.<br> After four months my address has still not been changed and i contacted standard bank to find out why. I received an email from Buyisile Mthethwa on the 4th of May telling me that my address has been changed, however the statements i received on the 5th of May and the 20th of May both still have the wrong address.<br> The bank warns of dire consequences if you do not update your details but it is impossible to do so. I am very unhappy with the service i have received.<br>
