Brakes and Check AEB system issue

[BostonMike]

So i was rear ended a couple weeks ago, not too bad, needed a new rear bumper and a couple brackets to hold it on.
So i get the car back, and the brake pedal goes to the floor, the check brakes light is on, as is the Check AEB system light, as well as the stereo no longer works.
The brakes i am assuming that they nicked the brake line, and maybe they cut a connection to the stereo amp (i think that is located in the trunk?), any ideas on the AEB system light?

Yeah, Automatic Emergency Braking can't work correctly if the brakes don't work correctly.
