Move a Badminton Match Without Losing the Court Fee

You captain a team in the Willowspan Badminton League. Your Thursday evening match cannot proceed because several teammates must attend a compulsory workplace meeting. League scheduler Dev Arlen has offered Tuesday evening or Sunday afternoon. Your team can attend Sunday, but the opposing captain has not confirmed availability. The sports hall will transfer Thursday's prepaid court fee to Sunday if Dev submits the change by Monday noon; a Tuesday booking would require another payment.
