Payments on Cheddar are irreversible so it's important to check you know the person you're paying.
However, mistakes happen. In the event you paid the wrong person:
1. Send them a payment request and add a note (and thank you GIF of course)
2. If that doesn't work and you know them, try reaching out
3. If that doesn't work, contact support with details.
If you believe you've been a victim of a scam, please contact support.
