Deposit & Withdrawal Issues
Payment issues account for the most support requests we receive. In most cases, you can resolve them on your own.
If your balance hasn't updated after a deposit, refresh the page first and wait a few minutes. Even after a successful transaction via Mobile Pay or Nagad, it can sometimes take 5–10 minutes to reflect. If more than 15 minutes have passed, contact support with your transaction ID.
If your withdrawal is stuck, first check whether your account is verified. Incomplete KYC is a common reason withdrawals are held. Also check whether you've met the wagering requirements on any bonuses in your balance.
- If your deposit hasn't gone through, wait the first 15 minutes before taking action.
- Save Your Transaction ID
- Always use a verified number for withdrawals.
- Check whether your bonus conditions have been met.
- Report any issues to support within 24 hours
Withdrawals must always be made through the same method used for the original deposit. Requests made via a different method will not be processed.
Understanding Bonuses & VIP Benefits
5666bd com offers a welcome bonus for new users. You'll receive a set bonus amount on your first deposit. Note that bonus funds cannot be withdrawn directly — you must place a certain number of bets first, which is known as wagering.
Daily and weekly cashback offers are also available. Regular players can qualify for the VIP program and unlock greater rewards. VIP members benefit from faster withdrawals, higher limits, and a dedicated account manager.
If you have any confusion about a bonus, the support team can walk you through it in detail. It's always best to read the bonus terms and conditions beforehand.

KYC Verification – Why It's Required and How to Complete It
KYC stands for Know Your Customer — it's the process of verifying your identity, and it's a standard part of international financial regulations. At 5666bd com, you'll need to complete this verification before making large withdrawals.
The process is straightforward. You'll typically need to submit a scanned copy of your National ID Card (NID) or passport. Photos taken with your mobile phone are accepted. Verification is usually completed within 24 hours.
Documents Required for KYC
- National ID Card (NID) – Front and Back
- Passport (as an alternative)
- Selfie photo – holding your NID
- Mobile number verification (not required if already completed)
Photos must be clear. Blurry or cropped images may delay the verification process.
