Is there a contract? If there is a contract, and it is stated in the contract that the other party fails to provide the video, it is a breach of contract and requires the other party to bear the liability for breach of contract according to the contract.

If there is no contract and there is a video in the wedding list promised by the other party, you can also find the other party to bear the responsibility for breach of contract.

You can complain to the industrial and commercial bureau, to the consumer agreement, to the mayor's hotline, and to the media. Really can't. You can ask him to refund some money or take other remedial measures through litigation.
