I confirm that the ad of such escort named Priyanka is

A SCAM 

. This is how operate:
1. Firstly, the scammer share with you the services, ask you for the schedule. Automatically, you receive two ephemeral pictures of a girl. I guess with the purpose of desire her more.
2. Then, when you arrange the time for the meeting, the scammer ask you for "an small amount" of the service. In the ad never mention it, by the way.
3. A realtime location will be shared with you, even if the meeting will be in hours.
4. The scammer will ask you for 50 but just because he/she just want anything you can say. "No way Jose, 10 bucks". And he/she accept it. That was a big red flag.
After that, obviously nobody is going to meet you in the address.
I LOVE indian girls, but you wont see an escort indian girl atleast in Ottawa.
