Locanto — fake id/defamation

Respected sir,

This is to inform you, some one is trying to create fake id of my mother on locanto, for escort services.
How i got to know about it? I have my mother's gmail synced in my phone, the person who tried to make this account had used her id to register, i suppose.in order to complete the registration, the email went for confirmation on her id, due to which i received the email (Screenshots attached), and that's when i got to know about it.

I request you to help me track down the ip address of the person and take a strict action against it as this is harassment and defamation of a reputed woman.
