It's completely normal to have questions or run into issues while betting or playing casino games online. Maybe you got stuck during a deposit, can't quite understand a bonus term, or you're having trouble logging in for the first time.399 com's Help Center was built exactly for this — so you're never stuck on your own and can find solutions fast.
Our support team is built with Bangladeshi players in mind. They speak Bengali, understand local payment systems, and can walk you through any issue clearly. Day or night, whenever you need us — we're here.
Opening a new account at 399 com only takes a few minutes. That said, small details can sometimes cause confusion. Here's a step-by-step walkthrough:
Click the "Register" button in the top menu. Fill in the form with your mobile number or email address.
A one-time password (OTP) will be sent to your mobile. Enter it within the time limit. If you don't receive it, click "Resend".
Choose a strong password of at least 8 characters — mix in numbers and special symbols. Never share it with anyone.
Add your name, date of birth, and payment method details. You'll need this information later when making withdrawals.
Tips: If you've forgotten your password, click the "Forgot Password" link on the login page. An OTP will be sent to your registered mobile number so you can reset it easily.
399 com supports all major payment methods used in Bangladesh. You can deposit easily via bKash, Nagad, Rocket, Upay, or bank transfer. The minimum deposit is just ৳100, and funds are typically credited to your account within 2–5 minutes.
If your balance hasn't updated for a while after a deposit, contact us via live chat with your Transaction ID. Our team typically resolves these issues within 15 minutes.
Keep in mind : always use your own mobile banking account when making deposits. Using someone else's number may cause verification issues. Each payment channel has a designated 399 com account number — copy it carefully from the deposit page.
Withdrawals at 399 com are significantly faster than on any other platform in Bangladesh. Funds are typically transferred to bKash or Nagad within 5 to 15 minutes of your request. Bank transfers may take 1 to 2 business days.
To make a withdrawal, your account must first have a completed KYC verification. Simply upload a photo of your NID card or passport to get verified. Once done, you can withdraw directly every time going forward.
The minimum withdrawal amount is ৳500. Winnings from bonuses are subject to wagering requirements — these are detailed in each bonus offer. If you're unsure about anything, just ask us on live chat and our team will be happy to explain.
399 com's bonus offers are designed specifically for Bangladeshi players. New members receive a welcome bonus as soon as they register, plus there are daily deposit cashbacks, referral bonuses, and seasonal promotions.
The most common bonus question we get is: what is a wagering requirement? Simply put, you need to place a certain amount of bets using your bonus before you can withdraw it. For example, a ৳1,000 bonus with a 10x wagering requirement means you must bet ৳10,000 in total before the bonus becomes withdrawable. This condition is clearly stated alongside every offer.
For any bonus-related questions, reach out via live chat or email at the Help Center. We'll walk you through everything in Bangla.
New to betting? No worries. Betting on 399 com is straightforward, but knowing a few basics will make the experience even better. Odds are a number that tells you how much you could win on a bet. For example, at odds of 2.5, a ৳100 bet returns ৳250 if you win.
Know your bet types — a single bet means wagering on one outcome in one match. Combining multiple matches into one bet makes it an accumulator or parlay. Live betting means placing bets in real time while a match is in progress — this is the most popular feature on 399 com, especially for cricket.
Please note: Betting is for entertainment. Never wager more than you can afford to lose. 399 com is fully committed to responsible gaming. To set your limits, Responsible Gaming View page.
399 com uses multiple layers of security to protect your account. The most important step is enabling two-factor authentication (2FA). With 2FA active, no one can access your account even if they know your password.
A few important reminders: never share your password or OTP with anyone. No 399 com staff member will ever ask for your password. If someone claims to be 399 com support and asks for your password, it's a scam. If you notice anything suspicious, contact us immediately.
If you notice any unusual activity on your account — such as an unrecognized login or an unknown transaction — change your password immediately and let us know via live chat. We'll investigate promptly and lock your account if needed to keep it secure.
Don't wait — contact us directly to resolve your issue right away.
