I just bought a 2G daily traffic package in 3 yuan, and I can use SMS to remind you. Wechat 10086 wechat official account also saw the traffic, and even said that I exceeded the traffic by 60.

There are only two possibilities! The first is that you have owed money before, but I don't think this is likely. If you owe money, they will send you a message! The second possibility is that you have been fooled by mobile customer service. Now you can call 10086 and ask them what's going on. If it can be solved, ask them to refund your phone bill. If you can't solve it, you can call the manual service to complain about them!
