Just tangentially related but recently I tried to buy something from an online store called Adorama and when I tried to place an order I got the notification of the charge from my bank after clicking the order button but the page didn't do anything, initially I though "well lets just get in touch with customer support, pretty sure they can see the charge and let me know what happen with it" oh boy was I wrong, their customer support only has access to orders not transactions, so when a bug in their website charged me without creating an order there is nothing they can do at all; all they did is recommend me to ask my bank to do a chargeback, but my bank says I need to wait 30 days after the transaction to so. So yeah, my lesson was the same, I should have had stick with Amazon because smaller stores just can't be trusted with handling purchases correctly.
