Please note that refunds can go to the customer for up to 30 days. You can download a confirmation letter in Merchant account interface, section "Transactions" for captured refunds, payouts, payments and provide it to the issuer bank.
	What happens if a withdrawal was sent to blocked/closed/lost/inactive card?	Such incoming funds (on blocked/closed/lost cards) should appear on a special bank's account (unclaimed account). The cardholder should check his agreement with a bank or request an issuer this information.
	If the bank holds funds for the declined transaction, what can we recommend to cardholder?	The issuer must release the funds after receiving our confirmation (download "Unprocessed funds" from Merchant account interface, section "Transactions" for declined payments), the customer should insist on releasing the hold.
	Do you perform converting currencies and add extra fees?	We do not make conversions or add fees. The data sent to a bank is exactly the same currency and amount you send us in your requests. All extra fees can be added by issuer bank and we cannot be responsible for this or predict/inform you.
	How can we get information on chargebacks and antifraud settings?	If you cannot find needed information in Merchant account interface (Section Disputes) you may contact our Risk team directly: risk@unlimint.com.
Decline reasons	What decline reasons do you have?	We accumulate declines coming from different banks and payment systems and show you grouped meanings for your convenience: "DeclineCode" in https://integration.unlimint.com/#Decline-codes. More explanation in Decline reasons
	We received "Declined by Antifraud", what do you recommend?	Code 03 (Declined by Antifraud) means that our Antifraud system was triggered. Concerning Antifraud work kindly contact our Risk department directly: risk@unlimint.com. Code 16 (Declined by bank’s antifraud) means that some Issuer or Payment system AF rules are affected. Need to contact an issuing organization.
	When making withdrawals we received 07 code "Limit reached" ("Operation is not allowed" in response), what do you recommend?	The reason is in limits: a total amount of refunds and payouts for the last several days exceeds percent of a total captured amount (settings depend on your agreement). You need to accumulate more deposits to be able to make refunds and payouts or you can wait for some period and your limit will be recalculated. The available amount is shown in Merchant account interface - Dashboard - Refunds&Payouts. Please address to your manager for more information.
	We received "Cancelled by customer", what do you recommend?	In general, decline reason "Declined by timeout" means that the cardholder didn't enter the details for payment (it's possible that the client push Cancel button or close the payment page or wait for a long time on the payment page).
	We received: "Declined by bank (reason not specified)", "Common decline by bank", "Bank’s malfunction", "Card limit reached", Incorrect card data", "Insufficient funds", what do you recommend?	Transactions are sent from our side in a general format. It depends on issuer bank and its settings – to approve or decline an operation. A client should contact the issuer directly for more information.
	We received: "Declined by 3-D Secure", "Only 3-D Secure transactions are allowed", "3-D Secure availability is unknown", what do you recommend?	Transactions were declined because the client didn’t pass 3-D S secure checking: 1) the result was not received; 2) issuer’s ACS was not available to respond correctly. If 3DS checking is not passed operation is declined on our side due to your 3-D Secure mode. You can also check 3-DS settings with our Risk Team: risk@unlimint.com.
