i would think that its time to raise some hell with the lot if they dont fix it. I have always found that a beautiful saturday afternoon in the middle of the showroom is a great place to voice what is going on. Its amazing how quickly your problem is addressed when they have buyers in their grasp. Of course this is a semi final answer when other avenues have been unsuccessful. Take my word for it when it comes down to it this does work. remember to use your outdoor voice!
