Car went down local garage today to get the brake system bled with new stuff

Now, I've got it back and its 100 times worse

Brake pedal nearly goes to floor and no bits at all

Need exact procedure how to bleed AP-4 pot calipers with a rear disc conversion

Please help and there's got to be something they haven't done or something has broke

Also, the servo tilts forward at the top when brake pedal is pressed, moves about 1/2 inch!!
