Just a little background info. At one time the Company had over 20 auditors for a crew force of 3000+. Now, with the introduction of the numerous E-expense report systems, there are less than a handful. Expecting an immediate response may be optimistic. Sending them an email with your side of the issue... priceless.
For what it's worth, I've always found it much better to have the auditor in your corner instead of working the other side of the ring. Translation: Asking for their
help with an audit issue was always better then telling them what they did wrong.
