Add charges to a credit card transaction.

[Partyco]

We are a business, and swiped a credit card on location for a transaction from the customer.  All good, 

except we realized after he left, we under-charged him for a high ticket item.  I understand how to do 

a 'refund' of a purchase, but I wanted to know if there is a way to charge an additional amount to his card,

or send a money request or somehow get in contact just from his transaction?  His name is unverified, 

so probably does not have a paypal account, and it was charged to his Amex card successfully.   My 

invoice just states 'cleared' and a partial card number.  Any suggestions?  Thank you.

Unfortunately you won't be able to charge the additional amount.  Assuming this was a one time purchase, not a return customer and you didn't collect an email address, if you do have the customer's name that may be your only starting point.
