Thank you for your's valueable comments,
If in case Debit card is not acceptable than wt to do?? is there any way to send D.D after my application.......
Faani, buddy, I am a live example whose DEBIT CARD was successfully charged. It is VISA, and I called my bank upfront to confirm charges from Canada by CIC are accepted. I was first told that the removal of freeze is valid for one day, but after little research (I told them to triple-check that and that I would wait on the line) they confirmed Canada is free to go, and no limits are imposed on Canadian 'vendors'.
You filed your application with the debit card, and there is virtually no way you can, and you should not I believe, withdraw your application for this reason, despite certain unsuccessful cases. It is your bank and CIC who should be connected for your money to leave your account, so ensure this is done on your bank's end.
I agree with other forumers that using a credit card could be a better option, but you are now where you are, soGOOD LUCK!
