What is the most effective way to complain about travel?

According to your account, my personal opinion is as follows:

First, about the reasons for the complaint:

Not being fully compensated is only one aspect of the problem, not the root cause of the problem. Therefore, it is not recommended that you take "no full-time escort" as the main basis for your complaint. Your complaint should mainly focus on whether the travel agency has fulfilled the service content and service level agreed in the contract. According to what you said, the details are as follows:

1, agreed to have a full-time guided tour service but did not;

2. The first day of the trip was delayed due to vehicle failure, and the scenic spots were missing;

I didn't play well the next day (why didn't I play well? What exactly is the problem? )

4. Agree to include meals but not meals;

5. The local tour guide has a bad attitude and is suspected to be an unlicensed tour guide.

According to the above facts, put forward your claim (your actual loss and the liquidated damages that the travel agency should bear, be reasonable and legal, and don't overcharge)

Second, about the complaint channels:

You can complain to the travel agency you signed up for first, and let them give their opinions to see if you can accept it. Accepted, the two sides reconciled;

If you don't accept it, you can complain to the local tourism authorities (tourism bureaus) or seek help from consumer associations. It can usually be solved.

In case this channel doesn't work, you will go to court.

I hope it helps you!
