Yunnan Mobile Company complained.

I really sympathize with the landlord ~ An unequal treaty like this can completely complain to the Ministry of Industry and Information Technology (the Ministry of Information Industry no longer exists ~), but now the most direct way is to call 12315 or 123 to directly complain and report to the Consumers Association or the competent department of mobile communication and information! For a monopoly company like Mobile, we must safeguard our legitimate rights and interests. I hope my answer will help you. Thank you.
