@Sumit_7 You seem to be misunderstanding the timeline and the nature of the issue here:

1. Well Outside the 24-Hour Window: I attempted to reschedule on July 28 - which was 3 full days (72 hours) before the July 31 voucher expiration date. This was not a last-minute attempt, so late fee policies are irrelevant here.

2. System Block, Not User Error: The Webassessor system had all future calendar dates completely grayed out, making it physically impossible to select any date - even dates prior to July 31.

3. Delayed Support Response: Because the portal blocked date selection, I immediately opened a High Priority ticket on July 28. Databricks Support did not respond until August 1 - after the deadline had passed - making it impossible for me to take action while the window was open.

Kryterion Support has already reviewed the account and confirmed in writing that the grayed-out dates were due to the voucher parameters set by Databricks, and that Databricks holds sole authority to grant an exception, replacement voucher, or refund.

I am requesting a Databricks Community Manager to please help escalate ticket #00977505 to the training management team.
