Dear knaeem
I have already write them a letter and when the lady called me first she asked me my date of birth, then said your name is XXXXX and your wife name is XXXXX and then she said you can't travel with ur visa to canada, i said whats the issue or reason, she said there is some problem/error in your visa you have to return it back to embassy and i said i have already booked my tickets but she never listen, and at the end she said u have to send it quickly!!
I don't know what would be the real reason!!
