Hi, My wife and I got an OINP NOI in early this year and we also got a mail, after submitting that our application is incomplete and that our EE profile doesn't exist. Our profile is very much valid until November this year. We really tried catching the glitch and we realised we had entered my NOC code instead of the job seeker validation code, and which is why our profile wasnt visible as valid to them. We wrote to them, apologising for the error and got the nomination thereafter.
