Customer says they're not enrolled

1. Dashboard → Customers → All customers, then search by their mobile number, name or email.
2. If they show up: they ARE enrolled. They may have removed the wallet card. Send them the wallet-add link from their customer detail page.
3. If they don't show up: they never scanned the QR, or they used a different number (perhaps a typo). Re-enrol them manually with Add customer.

Duplicate prevention: Fidz uses the mobile number as the unique identifier. Two phones with the same number cannot create two records. If you find a duplicate, email hello@fidz.app — we'll merge them server-side.
