North American Bancard Take the money and run.... troy Michigan

We had a customer who was charged twice on an $1175.00 transaction.  We promptly informed North American Bancard and they told us they would refund her in 7 to 10 business days (which is crazy in itself).  That was March 23, 2013.  It is now June 18, 2003 and she has not yet received her refund.  We reimbursed the customer after her 10 day waiting period with the agreement she would pay us after she received the money.  North American has requested TWICE for the customers bank records (which she provided) to prove that the transaction did not go thru.  All we get is the runaround from their customer service department.  This company is a joke.
