Do you want to ask, "I paid the registration fee for Shandong Xingtu Education but didn't sign the contract. I tied my bank card and didn't give me my ID number. Can I get a refund?" In this case, you can get a refund.

When you sign the contract and pay the money, the contractual relationship is established. It's just that the contract has no specific details. If you ask for a refund, you have to compensate the other party for some losses. If the loss is small, the compensation is also small.
