You can ask but they can't do anything. Stop panicking about the bridgestones, while they aren't the best tyre around they certainly aren't the worst.
I experienced a little slide around a wet corner today on the Bridgestone RE050 Shod R. It wasn't a quick corner, going around a tightish bend at around 25mph on the industrial estate by my new place of work - it was like tentatively walking bare footed on a wet glass floor when it started to go, I was shocked at how little speed it took. The Haldex 4WD can take care of the traction, but can't help general grip.
For a top tier brand of tyre i've never had any other tyre come close to Bridgestone's lack of grip - Dunlop SP01, Pirelli P7, Conti 3, Michelin PS3 have all been miles ahead in comparison. You can be sure VW/Audi don't have Bridgestones on when they conduct their economy and performance tests to determine their official figures. Fair dos on a 1.2TSI or 1.6TDI Golf SE, but when you're paying upwards of £25k for a car, you expect some rubber that will not hinder the car's potential performance, even if it ended up costing an extra tenner a corner.
