I have a voided invoice, and one of my customers keeps getting a notification telling him that the invoice is unpaid (2nd notice, 3rd notice, etc).
1. The invoice belongs to A DIFFERENT CUSTOMER
2. The invoice pay link seems to be invalid? not sure...
3. The invoice is VOIDED, and it still doesn't solve the issue..
The customer who's getting the invoices has a perfect record and has no unpaid invoices. What could be the issue?
