I'm so sorry to hear your story.
Do you have the Ministry/Department of Education in your country? Why don't you inform the appropriate authorities about this kind of a mess? Let them know about this mess. I believe the government will take relevant action against these thieves.
I tell you, if the Ministry/Department of Education investigates and takes appropriate measures against the test center it will be a good lesson to ETS, because ETS will lose income.... the thing that ETS is not prepared yet to face.
ETS makes a lot of money in the Phillipines from various standardized tests.
If I were you, I would have informed the police...
