Hi. I just had a customer pay their invoice and the first time it said the card was invalid, so they retried. I have one paid invoice from them but they immediately contacted me saying they were charged twice. What can I do to help them?
The first charge is a temporary hold that was created when the card payment failed and will automatically fall off their online billing, similar to a gas station $1 temporary hold that is created to test the card that goes away automatically.
