I bought a car and said the invoice was gone.

After buying a car, the 4s shop will not issue a car purchase invoice to the motor vehicle. You can find a 4s shop to return the car. Without a car purchase invoice, you can't go through the formalities of temporary license plate and new car registration, which is equivalent to a pile of expenses for a black car with incomplete procedures. If the 4s shop doesn't give the car purchase invoice or can't provide the car purchase invoice, you can complain to the Industrial and Commercial Bureau about triple compensation for you, because it is illegal for the 4s shop to sell cars and deceive consumers into paying compensation in advance. Generally, 4s stores will provide car purchase invoices and certificates. If you can't provide the invoice and certificate of approval at that time, the 4s shop will explain the situation to you and appoint a time to receive the certificate and invoice. If the 4s shop doesn't give you an invoice, you can call the police. It's best to complain to the industrial and commercial bureau and sue the 4s shop in court. These departments will support consumers.
