Hello, regarding your question, I can only say that the law does not clearly stipulate the legal responsibility of this monopolistic behavior. Since the water supply company is contracted out by the town government, you can only go to court to sue the quality inspection department for poor supervision, which is an administrative violation. As for the water company, you can only report and expose to the relevant departments, and the specific charges cannot be verified. Or go to the higher government and regulatory authorities to complain and prosecute.
I hope it helps you.
