There are two companies with the same name, one in Canada other one in UK.But they haven't asked for any money till now. And, I don't understand what they will do just by stealing passport information.
Those scams have usually 2 goals:
1. to make money of you
2. to get information from you and then to thief your identity.
First case is obvious, but funny enough less harmful.
Second option can do you much more damage in a long term (think about how they will use your fake passport and how that might end up on your record without you knowing).
That is why the advice is not to send personal documents.
