The VW Polo 6R has a suspension system first seen in the Mk 4 Golf, running a torsion beam, coil spring and dampers setup on the rear along with a MacPherson Strut setup on the front. With this setup, the strut is mounted in a fixed, immovable position into the cast housing that also carries the hard-points for the ball joint (control arm mounting), tie rod (steering arms), brake calipers (and carriers in diesel and GTI models) and also holds the wheel bearing and hub assembly.

When performing a "wheel alignment" on these vehicles, there is only 1 thing that can be adjusted and that is the toe in/out of the front tyres. The only way to adjust camber is to move the whole front subframe which generally highlights bigger issues than just camber being out. The other issue with moving the subframe is that while giving one wheel more negative camber, you automatically give the opposing wheel positive camber.

Refer to teh following documents for further information but in short, unless someone is adjust the toe of your front wheels, if you get charged for a wheel alignment, you are being ripped off.
