How to solve the problem of automatic deduction of mobile phone fees for sending short messages? I didn't send a text message at all, and I brought back a guarantee.

Call 10086, and follow the prompts to find human resources customer service, and ask him to help you check the charging records of the last two months. If he says Monternet charged you XX yuan, or you customized XX business, you can say I didn't order, I didn't order. Some customer service will give you a refund within 7 days, and some difficult customer service will let you check the list. If you have any questions, you can find them in "Charge Deduction Inquiry Feedback". You have to argue with her. I have a question now. What if I check the list? What I want to know is what to do with the detained money. Since I made a business request, why didn't you send me a text message telling me to deduct the fee without saying anything? I won't stop talking to you unless you give me a reasonable explanation. Be tough. If he can't handle you, he will give you a refund and leave the next one at the right time. Then tell him that you want to block all the services of Monternet. There will be no more charges. If it will be recharged, it is a virus in the mobile phone. Take it to the mobile phone store and let them take a look at it for you.
