I have applied in November but made a stupid mistake on the physical presence calculator in that I put the date of my PR one year back by accident (just on the calculator in the application i put the correct date). so they have returned my complete application with a letter saying that I was not a PR on the date entered in the presence calculator and that my application is refused and that i can reapply wight he correct information. I got a full refund (630$). So since I got a refund and my application was not returned due to being incomplete, I do not know how I should check the box on have i applied before. I have applied but was not processed since I got a full refund.
