Any card protects rights, Sichuan Telecom arbitrarily stops opening voice packets for 30 packets 150 minutes for half a year, and 50 packets for 300 minutes. What should we do now?

The correct way to complain is to make a phone call. First 10000 (generally, you won't get a satisfactory answer), and then go to the Ministry of Industry and Information Technology to complain online after the first step is not resolved (you can complain to Sichuan Communications Administration incidentally if you want to exert more pressure). Note that it is well founded. After all, the Ministry of Industry and Information Technology is the competent department of operators, which is more useful than 123 15. If it is not enough, the media and the courts will go back.
