Alenco review: Most insulting experience

I had someone from Alenco come out to do a simple estimate to see how much it would cost to replace it. Now, when I explain to someone exactly what my budget is and they come back with an estimate that is 4 times that amount, he has wasted my time and I do not appreciate being insulted. My home is less than 1400 sq. ft. and I research before I make the call for an estimate.
Not only was I quoted almost 50 THOUSAND dollars (not joking, still have the bid he wrote up) but he looked me straight in the face at laughed at me when I said what I thought it would be. So either they think I'm stupid because I'm a woman (far from it), or they have no problem OVERCHARGING people. Don't know where all these positive reviews come from. Try another website and you will see how many other people have given massively negative reviews.
I will not only NOT do business with them, but I will do my best to let others know how Alenco treats their customers.
I HAVE NEVER FELT AS DISRESPECTED as I did in this estimate.
I guess we'll see if this review makes the "cut!"

RUN AWAY!
By the way, this is the most unprofessional "bid" I have EVER seen. I am also a veteran and this guy was SO proud of the "discounts" he gave me, which did NOT include any military discount. Which is fine if he weren't so proud of the ones he was "giving" me. Absolutely disgusting treatment. You be the judge whether you want to do business with a company like this.
Also, I tried to upload a photo of the actual bid but there seems to be an "error" whenever I try. Which is rather convenient.
