If anyone is following the saga I will keep a running post.
Yesterday after retracing everything in my mind, I came to the conclusion they really did do it while it was in their body shop. So, I emailed the Used Car Manager at Park Place Plano Lexus and told him my belief. I explained my position and that I wnated the windshield (and some other items) fixed or replaced. Further, I told him that I know PPL has a solid Customer Satisfaction rating so I expected no issues from them on the matter but that, if they were going to push back, to please call me.
A couple of hours later, I got a reply from him and he simply said, "he would handle it; and to tell him when it was in service and he would work with them." I found this very comforting and am happy to have it in writing from him that it would be taken care of.
Now, proof is in the pudding. I don't take it in until Monday, so will update this board with results either way if anyone is interested. It's always good to provide real results, good or bad, so that the Dealer reputation is positively or negatively impacted publicly. My 2 cents anyway.
Thanks all,
C
