1. Clear the browser cache: Open the settings option of the mobile browser, and find options such as "Clear the cache" or "Clear the history" in the privacy or advanced options to operate.
2. Use another browser: If the first method doesn't work, you can try using another browser to access the page. The new browser does not save relevant data, so the previous online customer service information will not appear.
3. Restart the phone: Sometimes restarting the device can also solve the problem. After restarting, visit the page again to see if there is any online customer service information.
If the above methods can't solve the problem, it is recommended to contact customer service staff in official website for help.
