1. It doesn't matter if you haven't used the temporary line.
2. Use a temporary limit, depending on your billing date. The consumed temporary line is included in the latest bill and repaid on the corresponding due repayment date, regardless of the expiration of the temporary line. Just pay the bill. Credit cards can also be repaid if they report the loss immediately.
