If the spindle itself were bent, you would have a serious problem that alignment would not correct. The spindle is part of the 'steering knuckle', so it may have been bent where it is inserted in the knuckle, or the knuckle arm may be bent, or they may be wrong. If they felt they could 'compensate' for an out-of-spec part by alignment, they may not have bothered to accurately assess the defective part - they may have just guessed. You might ask them just what measurement they had a problem adjusting, then ask here for opinions on the possible cause.
