XL would do this for you pretty easily. Also, don't just credit the loan and assume the SM is now prepaid. I'd offer a refund between what was owed and what was paid. (Assuming it was paid as agreed.) Also, as a reservist called up you should be looking at the date they got orders, not when they reported for active duty.
