lol ... this happened with me too in the past when i have to add my spouse .. first mail they didn't replied for twenty days and then for second email they replied next days ..AINP2014 said:you are right.
but the strange thing that i sent the email last friday @ 12:28PM and get a response the same day @ 1:12PM !!!
but in ur case its a generic response so just apply the notes the same thing i did..
