Conexis flex spending is an absolutely ridiculous amount of work

Once again, I'm dealing with trying to justify expenditures from my flexible spending account. Five months ago. At a place called "CENTRAL BILLING OFFICE" in Charlottesville VA. My investigator rates are way higher than the $10 a year I'm saving by using flexible spending pre-tax. It took 4 emails to get a phone number to call the place, and two transfers to get help logging in. It seems like 50% of my flex spending expenditures have to be justified months after they've happened. Why is this so hard?
