I too have been locked out since September 14.  I logged in on September 13 and September 14 my email is not found.  Not only did I lose my QBO account, but my whole intuit account has disappeared/been deactivated.  I have spoken to customer service many time and uploaded my id several times and nothing.  Each time I am told this has to be escalated to tier 3 support, but nothing is changing.  I get an email requesting my id, I upload and I get denied.  All of the online help says to login to your account, which is impossible since I have been locked out!  I tried creating a new account, but can't do that because my email addresses are "associated with another account".  This is so frustrating!
