How to complain about Chongqing Meitu Travel Agency?

Did you sign the contract? When signing the contract, did you inform me that there were tickets for scenic spots at your own expense? Lunch is a one-day tour without eating, eat at your own expense, and choose whether to eat in the cafeteria voluntarily? You complained that the travel agency didn't sign the contract and didn't inform in advance that there were scenic spots at its own expense, so you can't complain about eating. Tour guides can complain without explanation. The main complaint is whether the contract has been signed. If the contract is not signed, the Tourism Bureau will impose a fine of 20,000 yuan.
