I left my charger at the hotel, and the hotel has been dragging it to send it to me. Is it useful to complain to the industrial and commercial bureau?

You can call the local industrial and commercial bureau to report complaints.

Complaint, in one word, means to file a complaint with the government, and now it refers to the court or relevant departments and personnel.

Consumer complaints can be made by telephone, letter, interview and internet. But no matter what form it takes, the following contents must be made clear: First, the basic situation of the complainant. That is, the complainant's name, gender, contact address, contact telephone number, postal code, etc. The second is the basic situation of the respondents. That is, the name, address and telephone number of the defendant. The third is the time, brand, origin, specification, quantity and price of the goods purchased. The fourth is the specific situation of the damage, the time to find the problem and the process of negotiation with the operator. Fifth, shopping vouchers, warranty cards, copies of agreements, etc.
