What should I do if I suddenly see the SMS banking information sales fee 13000 two months ago?

I would like to ask what should I do if I suddenly see the bank information consumption 13000 two months ago? Suddenly, I saw that the consumption of SMS banking information in the first two months was 13000. I can take the following steps to deal with this problem:

1. Confirm the accuracy of consumption: Check your consumption records in the past two months to confirm whether it is possible to have this consumption of13,000 yuan. Check the transaction details of bank statements, credit card bills or other payment methods, and check the amount and date.

2. Contact the customer service of the bank: If it is confirmed that this consumption is unauthorized or abnormal, contact the customer service department of the bank as soon as possible. Explain the situation and provide relevant transaction records and SMS banking information. Ask the bank for detailed information about this consumption, and express your doubts and ask to solve the problem.

3. Provide evidence and appeal: According to the requirements of the bank, you may need to fill in an appeal form or provide other supporting documents to support your appeal. Provide any relevant evidence, such as proof that you are not at the place of consumption, relevant receipts or other supporting documents to help banks investigate and solve problems.

4. Solve it as soon as possible: Although it has been two months, it is still very important to contact the bank customer service as soon as possible. Explain the situation and strive for a reasonable solution from the bank. Banks can investigate and deal with the consumption in the past two months according to the actual situation and policies.

5. Monitor account activities: Before the problem is solved, pay close attention to account activities to ensure that there are no other unauthorized consumption or abnormal transactions. If other abnormal conditions are found, report them to the bank in time.
