I want to complain about you. I'll complain until you get your money back. Please call Shanghai Tourism Bureau.

First of all, have you signed a travel contract with the other party? If a contract is signed, is there an agreement on the liability for breach of contract? Personally, I think you have violated the contract, because the agreement is to leave at 7: 00 a.m. and gather at 6: 40 a.m., so both parties to the contract must strictly follow the agreement. If you are late, you have violated the contract and are in breach of contract. Even if you complain to the tourism bureau, there will be no good result. If you don't sign a travel contract, you will be more pregnant. There is no place to sue, no contract constraint, and no legal effect! !
