Dear mudfish,
Could i request a refund on my balance (5.67$) ?. It is not much, but i have no plan to use Mudfish anymore because the change on your policy.
No problem. However, since it has been more than one week since your payment, please note that you are eligible for a balance refund. In many cases, users miscalculate the expected refund amount, so we kindly ask for your understanding as we verify the calculation before processing it. The method of calculating balance refunds is explained in detail in our Refund Policy document, so please review it carefully to avoid any misunderstandings.
In your case, you made a payment of 9.99 USD (KRW 13,773) on your last transaction date (2025-05-13 16:13:10 UTC). Since the minimum usage fee of 5.99 USD was not met, the refund policy calculation results in a refund of 4.00 USD. The remaining 1.67 USD will remain as Mudfish credits.
If you would like us to proceed with the refund as described, please reply to confirm.
