Antenna broken away

Something very stupid happened to me today. I’ve had a Fox as a rental car for a few days. Parked the good piece in my duplex garage, there was already a lot of noise (as you probably noticed, the lower level of the garage) and I remembered again, the antenna. Was not too bad when driving in, but driving out, could not unscrew it, so someone held it while driving out, but then slipped away and the stupid antenna broke out of the anchor. What’s the fun at VW going to cost me? Thank you very much.
