Hello everyone, I need some help
((. Last week, I had prepared for application to extend my visitor visa record in Canada. When I was on the payment page, I entered my visa number to pay the fee. Then I received a receipt, but suddenly I forgot to save that receipt and returned to my main page. And I saw my application was not submitted yet. I was so frustrated. I did not know what to do because I know I was my fault to not save the receipt but return to my main page.
Anyone know what do do? I am afaird to pay it again if it would not work. And I dont want to lose another $100 fee for my application. Thank you guys very much.
