Reserved the item, agreed on my T&C and decided to cancel since she cannot pay it on time. Gave her enough time to pay than the usual next day payment. Pls. consider this as a lesson and never commit again next time.
Update: And for the record, my payment terms are flexible, you can always update but you don't unless I remind you. There's so many ways to pay. At least have the decency to UPDATE without being told. That's called respect that you don't have. Being nice to you is a waste of time.
