A crypto card purchase follows card rules, not blockchain rules, and that changes how you get your money back. Here is the order of steps, and what to keep on hand.

Write to the merchant and state the problem plainly: what you ordered, what went wrong, and what outcome you want. Attach the order number, the confirmation email and any photos or messages that support your case. Ask for a refund to the original payment method, which here means the card you paid with. Most cases end at this step, and a clear, documented request makes it easier for the merchant to agree. This is general information, not legal advice; your rights depend on the merchant's terms and the rules that apply where you live.
A merchant refund travels back through the card network to the card. It is not a new blockchain transfer, so you should not expect a deposit to appear at a wallet address or on a particular network. The card only spends its available balance, and a returned amount shows up as a card transaction rather than a crypto deposit. If you paid with a Nexus Pay card, check the transaction history in the app to see the refund appear. Merchants set their own processing routines, so if nothing shows up, ask the merchant for confirmation that the refund was issued.
A dispute is a formal step for the case where the merchant does not cooperate: it ignores you, refuses without a reasonable explanation, or promises a refund that never arrives. It is handled through the card issuer, not through the merchant and not through the blockchain. Try the merchant first and keep the evidence of that attempt, because the issuer will want to see what has already happened. The issuer decides the outcome under its own rules, so a dispute is a request for review, not a guaranteed result.
| Situation | Route | What you do | Can it be reversed? |
|---|---|---|---|
| Merchant agrees to refund a card purchase | Card network, back to the card | Request the refund and check the card history | Yes, by the merchant's refund |
| Merchant ignores or refuses | Dispute through the card issuer | Submit your records and explain the case | Possible, decided by the issuer |
| Paid by direct on-chain transfer | Merchant's goodwill only | Ask the seller to send funds back voluntarily | No, the transfer is irreversible |
| Sent to the wrong address or network | None | Verify the address and network before sending | No, it cannot be undone |
Good records are the strongest thing you control. Keep the transaction entry from your wallet history, since it shows the date, the amount and the merchant. Add the following:
Save these before you contact anyone, because pages and chats can change or disappear. With Nexus Pay, the in-app history is a convenient starting point for the payment side of the file.
A card purchase runs through the card network and the issuer, which is why refunds and disputes exist for it. An on-chain transfer works differently: blockchain transfers are irreversible, and nobody can bring back a transfer sent to the wrong address. If you pay a seller by sending crypto directly, the only route to your money is the seller choosing to send it back. So the protections of a card purchase are separate from those of an on-chain transfer, and it helps to know which one you are using before you pay.
Check the merchant's return terms and the total amount before you confirm. Remember that the card spends only the available balance, with no credit and no overdraft, so you control the maximum exposure by what you keep on the card. If something looks wrong, such as an unexpected repeat charge, you can freeze the card in the app in one tap and unfreeze it later. Keeping only what you plan to spend on the card limits how much a bad purchase can affect.
