I haven’t received my BIL because i didn’t pay for my biometric, i had a call with the agent and was advised to pay the biometric fee, and so i did. Im exactly like you paid for the application only and didn’t know that there is a biometric fee.
I called IRCC today and it turns out i didn’t pay for my biometric, i would assume that’s the reason i didn’t receive BIL yet, so just payed it and uploaded the receipt through webform.
