Just so you know, home photography service coupled with courier/pick up is not a new concept. I have seen that a lot in India, so it wasn't too much of a stretch to think that maybe Indian consultate service may have something similar. Yes, it's obvious that Purolator won't come with a camera, but when you are booking the pick up-drop off service, it doesn't say anything about Purolator.
Also, it made zero sense to me to add a service for photography and photocopying on the pickup-drop off page when those services are available only at the center. There are a lot of people who don't stay near Brampton, or even in GTA for that matter. It's like Zara providing a mail in return option and sending you a shipping label so you don't have to come to the store, and then offers a service to print that label by coming into the store.
As you said, should have been more cautious for sure, but the lack of information about the service on the order page OR even AFTER payment is made is deceptive.
