I Was Entered In A Financial Transactions For An Service

But after payment, the party kept asking for more money but it was never-ending, I lost 12500, first agreed money 6000 later asked for security deposit 5000 and the other charges 1500 even after that the party did not budge kept asking more. I need to press charges can I (this was a Call girl incident) I've the person bank account details and mobile numbers. I know it was not right but I don't want others to deal with the same situation.. I am not looking to get my money back but want the persons to be held responsible for their actions.
