I dont know your date of application, if they did not return your application, there is a way to update your credit card payment form.
You need to do two things right away,
1) email scanned copy of updated credit card payment form with title urgent,
2) CPC-sydney has a FAX number (I believe it is (902) 270-3561) I got it from a different website, immediately fax filled form with signature and a letter explaining your situation with all personal details, also write uci on top of ur form
3) Immediately post the original copy
good luck.....
