DL has used "charge card" instead of the normal "credit card" so many times I thought I was complying with their preferred practice by using the term "charge card." They scored this wrong. Was that a trick question? (not uncommon here)
Frustrating, I know. I've fallen victim to similar bait n switched. I just tell myself it's in beta development, even if it's no longer true LOL.
How would you say "pay the bill AND the credit card"?, as in I'm telling someone to pay both things, is it just context?
