Hello , guys i sent a trp extention request for my daughter payed 28 cad for registered mail and signature , tracking says its out for delivery since 28 Sept , i filed a complaint with canada post. They are saying a large volume receiver sometimes does not provide a signature and your mail must have reached. should i freak out , how can i call ircc edmonton and confirm they got my application. i applied one month before trp expiry as mentioned.
