I am trying to add my Son as a Authorized User. Im legally blind. I cannot get a code sent to cell phone or land line so I got a letter with a 1 time passcode. I called with 1 time passcode after being told with that code I can add my Son and update my information. I called and they still said I had to get a text or call to update any information on my Account. I go through this all day every day. I think companies should be more available for persons with my conditions, if I cant use the card cause I'm blind that's pretty pathetic.
