Coins should not be deducted if there's no single conversation. Coins will be deducted if the match leaves the conversation even without a single conversation. To me, I think that's a waste of money. And that's also really bad for the App. As good as the app is, I have hate that one thing about it. If there's no conversation at all, then my coins should not be deducted for that conversation. So I rate 1 star
