Firestone Auto center brake repair kirkland, Washington

I had my brakes done at Firestone on 1/5/2011 one month later my brake pedal goes to the floor.So I took it back to see why they said I needed all this new stuff that would cost another 633.33 dollars after I spent 332.48 a month ago I asked them how it happened they had no excuse.Then I asked them why they didnt see it a month ago and again no excuse.This has happened A couple of times at the same place with a different car.Had work done then a month later something else goes wrong.I just thought that it was wear.But after this time I think they are ripping off alot of people.I do not know if it private owned or not but Firestone needs to look in to it.Its their name.I will not use this place again and I will not recommend them to anybody.I have my own company I will make sure that my emploees and customers know not to take their cars there.
