How to report a black tour group?

I've heard about the money paid by tourists in travel agencies and tour guides. Many friends have even experienced it personally. After signing up for a tour group, they were forced to buy goods by the tour guide during the tour, and the tour guide also deducted the tour fees from the tourists, which made the tourists' travel experience very poor, and even the local specialties could not be eaten after a trip.

Of course, incidents like this usually happen in low-cost tour groups and informal travel agencies. Such incidents do not happen in regular travel agencies. Only a few tour guides will conduct illegal operations privately, and qualified tour guides must obtain qualification certificates before they can take up their posts.

many friends will sign up for such low-cost tour groups in order to be cheap, and as a result, they are forced to shop by the tour guides during the trip, so they can't travel well. When most tourists encounter this situation, they will choose to submit to humiliation and will not stand up and resist. In fact, this behavior is very wrong, but it will make those tour guides even worse.

I've never met such a tour guide. Firstly, because I'm usually from go on road trip, or I don't travel with a group, I won't meet such a "black-hearted" tour guide. If I do, I will definitely take a local tour. The hotline or the mayor's hotline or 12315 will never compromise when making a complaint.
