That makes perfect sense and I get that. It's just, their math for the interest charge there didn't quite add up. Even with a flat interest calculation, it worked out to over 6% when the interest rate on the card is < 3%. I insisted on the workings, purely out of academic interest and they've promised to courier it. The charge in this month's statement which they didn't have an explanation for is being reversed.
