Brakes do squeak

I recently purchased a vw polo gti, the brakes made a noise from day one. When I sent it in they told me everything is fine and brakes squeak sometimes. A few weeks later, the squeaks are worse and there are rattles. When I called in they say that brakes do squeak. Is there anyone who can investigate the level of workmanship at south coast vw. My car is on maintenance plan till 2025 and I fear what more I am in store for with this level of service. I have driven another polo which is relatively new, and I hear no squeaks and rattles.
