so they got they told u that your control arm is damaged and charged for a wheel alignment!! if your control arm is bent, they wouldn't be able to align your car properly. i would take it elsewhere, ie try the ones recommended by the guys above. and if its confirmed that your contorl arm is bent get it fixed and demand a refund for the dodgy work done @ beaurepairs. if u have any issues call the dept of fair trading or the beaurepairs head office.
if you need a control arm, check out some of the wrecks in the for sale section. or call some local import wreckers.
