According to their 48 hour investigation, my package was delivered successfully. Kept pushing once again, and now they're saying they will escalate this to one of their Senior Customer Specialist or Supervisor. I should receive a status update within 24 hours, but wow, I never thought I would have to go through this much trouble.

That's actually smooth sailing compared to other SEs that've taken months to finalize.

do you think it is too late to ask about that one-time exception policy?

It's not too late - In fact It's appropriate.

When all else fails, that's the best time to request a one-time exception.
