Ngoc Nguyen ordered an expensive device which we shipped tracked, RR173297653CZ. Because she made a mistake in her email address (omitting one of the three leading n's), she did not receive our confirmation emails and filed a payment dispute with PayPal. When we informed her of the tracking status and explained that she made a typo in her email address, she accused us of being responsible for that and promised to close the dispute, but she did not. At the time of writing, we lost USD 162, making Ngoc Nguyen guilty of fraud, since the shipment is provenly on its way to her.
