Gave up with the attempted phone call as the hold I was on passed 60 minutes.
If you really ARE that overwhelmed with calls - start at 8 am instead of 9? Unreasonable request?

Staffing issues.

We start at 6:45 am on days that we expect higher than usual volumes of calls guests.

And when was your last day off again...?

Last one? Was just this Saturday.
Next one is tomorrow.
Next week is Wednesday and Thursday. Consecutives.
But then Friday and Saturday are both 2:45 to 10:30 pm.
