Before you buy
Use the contact form to discuss business type, country, locations, hardware, connectivity and required invoicing workflow. We will help identify what can be demonstrated and what needs local confirmation.
For an existing deployment
Contact the partner or support route named in your deployment agreement. Include the merchant and location, device model, app version, transaction reference, time, connection state and the exact message shown. Do not email passwords or full payment-card details.
For partners
Partners should complete first-line checks, record what changed and include evidence from the affected workflow. Escalating one clear case with reproducible steps is more useful than sending an unfiltered device log.
Invoice or offline issues
Keep the transaction visible and avoid creating a replacement sale unless the confirmed recovery process requires it. Record whether the item is local, queued, submitted, accepted or failed, and follow the country-specific escalation route.
Contact
Send support and product questions to info@datamega.net or call +86-592-5185416. Response times and service levels depend on the applicable customer or partner agreement.
