Find a substitute training on DNF5 173. If someone answers, will 5 173 send you a message? !

The premise is that you have selected the service of 5 173, and registered an account, and your account is bound with your mobile phone number, otherwise you will not receive the information. If you are bound and can't contact 5 173 for 90% of the time within a certain period of time, you will be given confidence in your mobile phone. Call if you can't get in touch. If you still can't get in touch, your account will be blocked. Thawing will take at least 3 days. I have had such an experience. Thank you.
