A chargeback is a charge that is returned to a payment card after a customer disputes an item on their account statement. A $20 fee will be incurred for every chargeback received.
Someone might file a chargeback because they:
Don’t recognize a charge.
Didn’t authorize a payment.
Didn’t receive an item or service they purchased.
Received a damaged or defective item that they purchased.
A processing error caused them to be charged the wrong amount or charged twice.
