CRA Result Code: 15

I am filing for myself and my wife. I have submitted my tax return however NETFILE is showing "rejected" for my wife with a result 15 and your account is locked message.
Yesterday, I talked with CRA with two different representatives which both confirmed that both of us CRA account is unlocked.
Its not our first tax return.
