Cancelled Invoice Paid by Customer but It doesn't show in our end

[Blosuc]

I canceled a customer's invoice. Resent a new invoice # and 2 minutes later. The customer said, They paid the canceled Invoice. I went back and it doesn't show anywhere that they paid the invoice but she claims she paid it. 

The customer was able to still pay the old canceled invoice instead of the new invoice that I had emailed them due to a mistake on spelling their last name. 

Long/Short, the customer was able to pay the canceled invoice. I find this very confusing since customer was still able to pay the canceled Invoice but I am unable to see that on my transactions tab or paid invoice tab but the customer has paid the invoice fully. 

How do we get around this matter if invoice is canceled but shows paid on the customer's end and not our side?

You should see the payment in transaction history. You should also have gotten a notification in your linked email that an invoice was paid. Have her show you her receipt before sending any merchandise or services.
