B If you have proof that the staff said these things, you can complain to them directly. As for complaints, you can choose to go to the Consumers Association to report group buying websites. This may be because they did not verify the location and misled consumers. You can also choose 3 15 to complain. But you must communicate with the group buying website first to see who is responsible for the problem. After all, the address is the main station, and there is no indication that you want to go to that branch office. That is, any branch can be used by default.
