Superb is pulling to the right whilst driving

My 2009 superb went in for an MOT, was told it failed on a broken rear spring. This was repaired however when the car was delivered back to me and I test drove it the steering wheel now sits to the left and not cantered and when I'm driving it pulls extremely badly to the right, it feels awful to drive.

I've spoke to the mechanic and he doesn't seem to have a clue.........

Has anyone any ideas ? Or had a similar problem
