Okay, hold on for a second. Let's recap cause it's getting out of control.
I said that in order to know what actually is happening I went through my MP, CIC told him they might have lost the file and they need to look for it. There is a procedure for that, when someone didn't get their AOR after 8 weeks. Which is two months people, not 4-5 weeks. So if you sent your fil on october 20 and didn't get AOR yet. Relax.
For the other ones, who are panicking about not receiving their AOR, I am reading in this forum send new applications, send them one inquiry per day etc. Those are not good solutions, they're just gonna generate way more work for CIC. What I am saying is if you are panicking about your file and it's been more than 2 months that you sent it, then get in touch with IRCC, there is a procedure for that and there's not need to spam them or go full hysterical.
