Frequently Asked Questions
Answers to common questions about accounts and services

mambaji is built primarily with Bangladeshi users in mind, so the main interface, navigation, bonus messages, and support chat are all available in Bengali. Regular users can navigate the entire platform without any knowledge of English. However, some in-game text from third-party game providers — such as certain slots or Live Casino content — may occasionally appear in English, as mambaji does not have direct control over content outside its own pages. That said, all key areas including betting odds, score updates, payment pages, and account settings are available in Bengali. Work is ongoing to bring even more of the platform into Bengali over time.

After logging in to mambaji, go to "My Account" to find your complete betting history and transaction records. There are two separate sections: "Betting Records" and "Payment History". Betting Records show when each bet was placed, the amount, the match, the odds, and the outcome. Payment History shows the date, amount, and status of every deposit and withdrawal. Records for the past 6 months are directly accessible. If you need older records, contact the support team — data going back up to 18 months can be provided. If you have any dispute regarding a bet result, you must notify support within 48 hours.
Responsible Betting: mambaji is strictly for members aged 18 and above. Betting is for entertainment — not a reliable source of income. Please play within your means. For more information, Responsible Gaming Visit the page.
