There are 4 channels, only one is enough, but if needed, use all.
Telegram group
In the group, quick answers to common questions are available; active moderators review daily, so for simple problems you may get a response within 10-20 minutes.
Find the official group on the navigation Community page; many Dhaka users get help there.
WhatsApp support
For personal questions this is the most useful tip; send Nagad and Rocket verification questions here.
Usually during work hours, responses come within 15 minutes; quick screenshots help understand the issue better.
Facebook page
New announcements, maintenance and small updates are posted here; weekly notices save you from asking the same questions.
If messages are written to the inbox, the team usually responds within 30 minutes, especially before the afternoon.
YouTube guide
In short videos, installation, login and help steps are shown for new users; this is very easy.
Even if you ask questions in the video comments, the team notes which step works.
