Legal suggestion: What should gehuayouxian do if it cuts off the optical cable and stops the cable TV service without authorization?

First, look at your cable TV service agreement with Ge Hua. Whether the term agreed in this agreement expires and whether there are relevant clauses to terminate the contract.

This kind of service contract is a breach of contract, and it needs to bear the responsibility for breach of contract, compensate the user for the loss and return the service fee paid because it has not expired.

If he can't continue to provide cable TV service, it's no use forcing him, and he can only be held liable for breach of contract.
