ford galaxy with a knocking noise after MOT?

hi I hope you can help... I went to do MOT, they failed the car (ford galaxy) because they said The anti roll bar has an excessive play in a pin/ bush, and the front macpherson strut has excessive movement at the upper attachment,
now after the work has been done I noticed that there is a knocking noise every time I make a turn, took the car back to the garage, and it still the same noise, took it back again, any ideas... kind regards ana
