sorry i meant my non ee application
+1 probably a webform is the best step to follow. Given that you already received AOR, you probably won't get a refund for your non-EE application.I think you can raise a webform explaining the situation or call IRCC and explain the issue.
I believe I've also read that IRCC can tell that you've gotten PR already and cancel your other PR application for you. In any case, don't count on getting money back.
