As it turns out its very simple to go on online chat to change addresses as was unable to edit myself, however the incompetence of the agents are something else. They entered my address incompletely, so it is missing the last digit of my suite number! When I went back to chat, they needed to send me a verification sms (only 1 account maintenance every 30 days is allowed without the need for verification) but doesn't work with citibank to textnow numbers.... urgh
@thizho do you reckon AMEX will accept address verification if its missing 1 digit? lol
