They don't seem to ever know what's going on
Twice I've been on the phone with them and they haven't been able to find my information, and they have called me on the other line while I'm on the phone with them. I have repeatedly given them info on when my return to work date is, but for some reason it doesn't stay saved in their computer system. Which screws up when I'm actually allowed back to work causing me to have a loss of earned wages.
