Cannot reschedule SC-200 exam due to expired voucher error (A73D)

Hello Support Team,

I am trying to reschedule my Microsoft Certification exam SC-200 (Microsoft Security Operations Analyst) scheduled for September 10th.

When I try to select a new date on Pearson VUE, I get the following error: "El registro se descontó con un vale y el vale presenta restricciones (********A73D). La nueva cita no cumple la siguiente restricción: El vale es Caducado y ya no se puede utilizar."

I previously opened support ticket #2609080010001575. Since my exam date is very close, I need urgent assistance to reschedule or extend the validity of this voucher so I can modify my appointment.

Please contact me so I can share my personal registration details via private message.

Thank you.
