When consumers encounter fraud, they can collect relevant evidence and take the following measures to protect their rights:

1, negotiated with the operator;

2. Request consumers' associations or other mediation organizations established according to law to mediate;

3. Complain to the relevant administrative department (industrial and commercial bureau);

4. According to the arbitration agreement reached with the operator, submit it to an arbitration institution for arbitration;

5. Bring a lawsuit to the people's court.

There are many examples of China Telecom offering premium video packages and premium education packages without informing customers. I suggest you always pay attention to whether your mobile phone card has value-added services and stop losses in time.
