1. Collect the contracts, payment vouchers and chat contents signed with educational institutions, and inquire whether the institutions charge fees illegally, run schools without a license, or increase fees.

2. Negotiate the refund request with the relevant docking personnel and ask the other party to refund the fee truthfully.

3. Complaining to the local education bureau, 123 15 platform, Tmall and other websites will affect the operation or enrollment of this institution.

If all the above methods are useless, you can bring a lawsuit directly to the court and use legal weapons to protect your rights.
