Message @ChainKeeperAIbot in private. For payment problems, include your invoice ID and the BscScan transaction hash.
The bot doesn't answer. Make sure an FAQ is set with /setfaq and that members mention the bot, reply to it, or use the trigger word (see /settrigger).
Captcha / link deletion doesn't work. The bot needs admin rights: delete messages and ban users.
I paid but the group isn't upgraded. Check that you sent USDT on BNB Smart Chain, the exact amount, before the invoice expired. Then send us the tx hash.
How do I get my group code? Send /plan in your group as an admin.
