Binance support e-mail
Those who have a Binance account can contact Binance by e-mail to receive support. A user cannot directly e-mail Binance. Instead, they send a support ticket which is answered by e-mail.
Your support ticket is more likely to be answered faster if you identify what topic you are asking about. One should have information ready as this helps the support staff solve problems quickly.
The support ticket should include a detailed description of the problem. One might also have some luck using social media as a way of contacting someone at Binance, although this is not officially supported.
