Contact
Chat first, on the site where you are logged in
Support sits on the official site. The chat can see the account, so you are not explaining a phone number to a stranger in a messenger.
Email is for an attachment: a status shot, a refused withdrawal, a request to close the account. Take the address from that site's footer, not from an advert.
Do not send a password. The reset goes to the saved contact anyway.
- Withdrawal stuck — ask whether verification is finished before you send a second document.
- Bonus gone — say whether a withdrawal went out mid-wager.
- Someone asks for an APK or an SMS code — that is not support.
