look at it from their point of view,
you've ruined their sale, and cost them fees, why should they agree to cancel?
they have every right to complete a non payment case against you to get their fees refunded,
No excuse to be rude, however you ruined their listing by refusing to pay.
Seller can open unpaid against you, if you don't pay within 4 days, case will close & you get strike,
2 of these in 12 months can restrict your buying.
