Bigo Unofficial Support Portal

If your Bigo diamonds have disappeared, first try refreshing your wallet, logging out and back in, clearing the app's cache, and updating the app. If they still don't appear after a few minutes to an hour, check your payment history and contact Bigo support with your ID and transaction details to report the issue.

Initial troubleshooting steps
Refresh and relog: Go to Me > Wallet and pull down to refresh. Then, try logging out and logging back into your account.

Clear cache:
Android: Go to your phone's Settings > Apps > BIGO > Storage and select Clear Cache.
iOS: Go to your phone's Settings > General > iPhone Storage > BIGO and select Offload App (this will not delete your data). Then reinstall it.

Update the app: Make sure you have the latest version of the Bigo app installed from your app store.
Check network: Switch between Wi-Fi and mobile data to see if that resolves the issue.
What to do if the problem continues

Verify the transaction: Check your bank or app store transaction history to confirm the purchase was completed. Look for a successful transaction ID and make sure it wasn't just a pending hold.

Contact Bigo support:
Go to Me > Feedback or use a support email like feedback@bigo.tv.
Provide your Bigo ID, transaction ID, screenshots of the purchase, and the exact time of the transaction.
Mention any error messages you received during the purchase.

Contact your payment provider: If you are certain the money was taken but the diamonds never appeared, you can also open a dispute with your bank or credit card company.
