Poor service and Extremely rude staff

Ive been trying for one week to simply change one of my bank account names and get a verification letter and no one has helped to date. Ive called the call center and they told me they cant do it their side I need to go to a bank. I went to the bank branch and after a hour of waiting they told me I cant do it there I need to send an email. I called today to follow up on my email and now ive been told I sent it to the wrong email address. Im about to cancel all my accounts with you due to your terrible support structure and rude staff that dont know what the hell they are doing. All your staff does is pass me on to other people everytime!!!!
