A simple request to update my addresses goes unanswered since December 2022!

Hi, what a mission to get one's address details and email address for statements updated! There is no online functionality to do this, and emailing *** on December 9, 2022, proved to be futile! Please update my postal, residential, and email addresses urgently and confirm once done. This is a basic request. Please get in touch with me to sort this out.
