Exadatum confirmation

Guys, due to an unexpected emergency in hospital from past 3 days I didn’t get any chance to accept confirmation to exadatum. What to do now? Is there any chance that they would give another chance to confirm or I should sit and wait from them?

Nope. Once the time to confirm is passed, there is nothing you can do.
You have to wait for them to come again.
Better to apply for other companies.
