Don't worry melody23,
The way they send your passport is through DHL. The VFS officers are not always correct. Keep checking the VFS tracking website.
Also if you have any issues, e-mail- info.canadabd@vfshelpline.com
I had some issues, and I e-mailed them. It took them 2 days to reply, and the reply was also very generic, but it is a proof that you had submitted your passport.
I know the fear that you are going through, and its very legitimate, however, what can you do? Its not in your/our hands. We are pretty much at the mercy of the visa/vfs people.
On a different note, my status on VFS tracking website has changed to
Visa application, tracking ID No xxxxxxx. Your Decision has been dispatched from the Canada Visa Office, Singapore on DD/MM/YYYY to the Canada Visa Application Centre DHAKA. You will get SMS & Email when your Decision will receive at Canada Visa application centre where it was submitted.
Should be receiving the passport in 3-4 days.
I was also thinking about your earlier post, where you mentioned that you already have a VALID TRV. I don't know if that would cause any issues, so please make sure to ask VFS or the canadian visa authorities about it.
