Why did the bank rule in favor of a customer's chargeback despite compelling evidence?

[Martini35]

I received noticed today that a customer's bank decided to rule in favour of them for a chargeback.  When I click the view response box on the order there is a statement that says the "What follows is compelling evidence, and a valid remedy for this chargeback".  Is this just a standard statement when one responses to a chargeback?  Is there any way to find out why a bank ruled in favour of their customer?  I spoke to the customer and followed up with an email and they confirmed they received the product and filed the chargeback in error.  I also submitted a shipping label with tracking number that shows delivery

Hi @Martini35

I'm sorry to hear that you've lost the chargeback case. Unfortunately, when a case is finalized and closed by the bank institution that is dealing with your issue is settled, there is no method of reversal for an appeal. 

The only way, is to contact the original customer and explain the situation and out of their pure good faith, you can ask them to confirm their refund and ask them to make secondary payment to you. You can even offer a discount or offer a free product to thank them for their gesture and for their time.
