How to Raise a Complaint or Support Ticket on Subisu

Subisu offers several ways to register a complaint, ranked here from fastest to most traditional:

1. Subisu Mobile App (recommended): Log in to the app, go to Support → My Tickets → New Ticket, and submit your issue directly. This creates a trackable ticket tied to your account, which is the most reliable way to ensure your complaint is logged and followed up on.
2. Phone call: Call 01-4235888 or 9801235888 for inside valley, or 01-4217444 for outside valley, and describe your issue directly to a support representative.
3. Email: Send a detailed description of your issue to support@subisu.net.np (inside valley) or ovcc.support@subisu.net.np (outside valley), including your account/username and the nature of the problem.
4. Facebook or Viber chat: Subisu's official Facebook page and Viber support lines are available for less urgent queries or quick status checks.
5. Visit a local outlet: For Outside Valley customers, local partner/provider offices can also handle support requests in person — check Subisu's coverage section for your nearest location.

What to Have Ready Before You Contact Support

Having the right details on hand before you call or submit a ticket significantly speeds up resolution:

• Your registered account username or customer ID
• Your registered mobile number
• A clear description of the issue (no internet, slow speed, TV signal loss, billing discrepancy, etc.)
• The status of your ONU/router lights, if it's a connectivity issue — specifically whether the PON or LOS (Loss of Signal) indicator is glowing steadily or blinking red
• Whether the issue affects one device or your entire network
• Any error messages displayed on your Set-Top Box, if it's a Clear TV issue

Quick Self-Help Before You Call

A meaningful share of common complaints can be resolved without waiting on hold. Try these first:

• No internet: Check your ONU's PON light — it should glow continuously. A blinking red LOS light usually indicates a fiber disconnection or signal loss issue that does require contacting technical support.
• Slow speed: Restart your router, check for router placement issues, and confirm you haven't exceeded your Fair Usage Policy threshold before assuming it's a network-side fault.
• Clear TV "no signal" message: Press the Info button twice on your remote to check RF Signal Quality and Signal Strength; if fluctuating, this points to a weak signal issue worth reporting.
• Clear TV channels missing: Press the NIT button on your remote to trigger a channel search, which often resolves missing-channel issues on its own.
• Forgot your app password: Use the Forgot Password option within the Subisu Mobile App rather than calling support for a simple reset.
