App refund scams: what they say, how to spot it, what to do

A stranger on Zelle, Venmo or Cash App says money was sent by mistake. Check inside the real app and ask official support before sending any new payment.

What they say

These are typical approaches, written as examples. The wording and claimed sender can change.

“I sent you money by mistake. Please send it back right now.”
“The refund needs a separate transfer to this other account.”
“Pay a fee to upgrade your account so the money can be released.”

How to spot it

A stranger creates pressure to send a new payment instead of using official support.
The only proof of payment is a screenshot, email or text.
They ask for a password, verification code or payment to unlock incoming funds.

What to do now

Do not send a new transfer to the stranger or another account they name. Do not spend the disputed money while checking it. A screenshot is not a reliable record of your account activity.
Open Zelle through your bank, or open your usual Venmo or Cash App directly. Check the transaction there. Ask the bank or app’s official support how to handle the unexpected payment and follow its instructions.
Keep the messages and any transaction reference. Do not use a support phone number from the stranger, a search advert or an unsolicited refund email. Never share a sign-in code with someone offering to fix the payment.

If you already paid or shared details

If you sent a separate repayment, contact your bank or the app’s official support immediately. Explain the unexpected payment and your outgoing transfer as two separate events. Ask what can be stopped or investigated.
If you gave away a login or code, secure the account from a trusted device and ask support about unauthorized access. Do not pay an account upgrade, release fee or recovery fee to resolve the incident.

Contact the bank, card issuer or payment provider promptly and ask whether the payment can be stopped or reversed. Recovery is not guaranteed. Change exposed passwords through the genuine service. Keep receipts and messages privately for your report.

Report the attempt at ReportFraud.ftc.gov. For internet-enabled fraud, also use the FBI’s IC3.

Questions people ask

What if the payment really appears in my app?

Ask the bank or app’s genuine support how to handle it. Do not make a separate transfer just because the stranger demands one.

Should I return money to a different username?

Do not follow a stranger’s instructions to redirect it. Preserve the request and use the official support process for the original transaction.
