Question on the BXP1 upgrade certificates.

I had used two of these for a connecting itinerary today LAX-DFW-TPA. I checked in and the agent stapled them to the boarding pass and voided them with today's travel date and itinerary as instructed.

We boarded LAX-DFW so the certificate was pulled by the agent working the flight. We left the gate and 4 hours later returned, having never left the ground, due the weather in Dallas. I subsequently cancelled my trip.

Agent at the airport said I could theoretically re-use the invalidated voucher that was still attached and wrote a little note on it but the other one was long gone since it had already been pulled during boarding.

What is the process here - should I bother calling BusinessExtra to replace them?
