My Battle.net account was stolen, and I have a mobile phone contract. What should I do if I can't remember my ID number?

If the ID number can't be changed, write your ID number and send your photo when you apply for cancellation. However, there may be an email for you to recharge. The title of this letter of guarantee is Battle.net SMS protection service in Battle.net online customer service-submit the form-the second drop-down box for selecting the theme-and then select the last drop-down box (delete the SMS protection service in Battle.net) to fill in the results. However, if you can't remember your ID card, it will be very difficult to deal with other problems in the future.
