I will ignore the slight condescending tone of some of your remarks
And I'll ignore the fact that your posts sound more than slightly like they are being made by someone affiliated with the installation company referenced earlier in the thread.
I must say, I'd be a bit more miffed if I was a consumer that was taken for thousands of dollars, and I certainly would not be posting back with glowing reviews six years later. I can only comment based on the information in this thread as I have no other knowledge of the issue or the parties involved, however even if that company was not using that "rebate" with malicious intent, it certainly speaks volumes about their business acumen when EVERY other industry professional that posted commented on how it was a "ponzi" scheme, and foolish to believe.
If you are indeed a genuine consumer, I do apologize for the harshness of my remarks, however if that is the case then the poster Windows4U looks like Nostradamus right about now.
