ok, Finally my father-in-law got the call to submit their passports and received the email as well. But cic account has not been updated so far. which I no longer care.
The rep said they have been trying to reach him for so long but couldn't find their number to call, and they have to do the search, funny, we provided the cell # and email on every document we attached. They are lying they could have emailed like they just did. Anyways, that's how may be they work.
The thing is I sent the first inquiry on 20th Dec, no response and then one on 20th Jan/14. And on 22nd jan they got the call.
Good luck to others who applied for Super visa.
