If other channels can't successfully complain about the mobile company, calling 12300 is just one of the most effective ways to complain. According to the institutional reform plan of the State Council announced on March 1 1, 2008, the Ministry of Industry and Information Technology of the People's Republic of China (hereinafter referred to as MIIT Ministry of Industry and Information Technology) was established as a constituent department of the State Council.
Complaints from the Ministry of Industry and Information Technology:
I found that my mobile phone couldn't get online, and I thought that I was in arrears and stopped. I still didn't respond after charging the phone bill. I consulted the customer service and found that my number was actually included in the fraudulent phone list by the Ministry of Industry and Information Technology.
This situation is generally that the mobile phone is monitored to frequently send sensitive words containing fraudulent information, or someone reports it. After verification, the Ministry of Industry and Information Technology will inform the operator of the number limit. It is also possible that the mobile phone number was fraudulently used by fraudsters to change the number software. If users have any objection to this, they can call 12300 to appeal to the Ministry of Industry and Information Technology.
