If the app suddenly closes or payment status isn't shown, stay calm first; what to say on the bd88 Contact page is important.
Nighttime Emergency Issues
At night, many outside Dhaka have slow network; if you send a brief message, user ID, and the time of the issue, the BD team can quickly identify it.
In such cases, the in-app Help Section is best; once the information is correct, you don't need to repeat the same things.
Payment not received
If top-ups from bKash, Nagad, Rocket are stuck, include the receipt and time; what can be explained in 1 minute is most helpful.
Here, not a long story; clear information helps the support team quickly resolve.
New User Questions
New users are often unsure where to find the app, how to install the APK, etc.; on the bd88 Help page these are easy to view separately.
If you read the FAQ from the start, there are fewer mistakes later; this makes login easier and reduces support load.
