Choose the relevant product
Serahin processes payments for pre-order purchases, while Manifly bills monthly software memberships. Cancellation and refund terms differ because the transactions serve different purposes.
Serahin · pre-order purchases
The campaign terms shown when an order is placed are the primary reference for cancellation, production, fulfilment, and refunds. The seller is responsible for the goods and campaign fulfilment. Contact the seller first with the order number and reason for the request.
Duplicate charges, incorrect amounts, or technical payment failures can be escalated to Sadatech. The payment service does not currently provide automated refunds; an approved resolution will include the method and expected timing. Never send a PIN, OTP, password, or full card number.
Manifly · monthly memberships
Auto-renew can be stopped from the Membership page. Entitlements remain active until the displayed paid-through date, and cancellation does not automatically refund the current period. Upgrades or add-ons are billed as a new monthly total without automatic proration or credit; downgrades apply on the next cycle.
Refund requests are reviewed manually for cases such as duplicate charges, an amount that differs from confirmation, or a technical failure that makes the paid service unavailable. Read the Manifly billing policy.
How to submit a request
Email sadanitech@gmail.com with the product name, the Serahin order number or Manifly billing reference, date, amount, and reason. We provide an initial response within 5 business days.
