The elements of fraud 

😂😂😂😂

why did he stop ? a real law professor would make videos

You will need to consult an attorney who is licensed to practice law in the forum State, i.e. the State where the rip-off occurred.

Warning: the law of fraud (both criminal and civil) is a highly technical one, so I would NOT proceed without an attorney. My best advice is to visit the closest office of your town's local bar association or the legal clinic office of your closest ABA-approved law school, as they can help you prepare and file your claim free of charge.
