Telegram Stars, proxy issuance, and successfully delivered digital configs are usually treated as fulfilled digital goods. Refunds are reviewed case by case when a delivery failure or payment issue can be reproduced.
If payment succeeds but the product does not unlock delivery, contact support through the Telegram bot with the purchase context and timestamp so the team can review the session.
For duplicate charges or recurring purchase issues, report the payment as soon as possible and include whether you used the website, mini app, or bot.
