Glass Block Headquarters

Pricing Scam. Beware!
I was quoted a price over the phone. Then the estimator came out to verify the price by measuring the basement windows. He said the price would stick and offered a free extra vent as an incentive. I had to wait a month for installation.
When the worker arrived, he immediately knocked out two windows. He asked me if the estimator measured from the outside or the inside. I said the outside. He said, well then, we’ve got a problem. The glass blocks are too small.
After numerous calls to his office he said he could fix the problem by inserting 2-​inch concrete blocks on both sides of the windows to take up the space. He had to do this on four of the five windows. Then he said «But it’s going to cost an additional $ 120. When I balked at that and said «you made the mistake — why do I have to pay for it?» He came down to $ 100.
I had to sign an «Add On Work Order» for him to continue working. If I had said no way, I would have been stuck with two missing windows in my basement and wait another month for replacements! After he finished installing he was going to leave without cleaning up the debris! I made him vacuum the entire basement.
I’m in the process of trying to get my $ 100 back by declaring fraud.

I would give zero stars if I could.
I received a sales estimate with absolutely no breakdown from the sales rep. Who just quotes a job with no break down of costs? I called the office to find out what exactly I was being charged for, since my quote was much higher than anticipated. The woman who answered the phone was less than helpful and very rude. She told me she could not give me any idea as to if I received the current promotions in my price estimate, but to go ahead and send the signed estimate with a deposit and she will let me know. What? Was I born yesterday? I told her absolutely not and that I would like the sales rep to call me and explain what he was including in my price as this did not seem to include the «two free vents» promotion they offered.
Three hours later the same rude woman called back and told me the promotion was included in my sales quote. So I then asked how much per window were they actually charging me, since they advertise $ 95 installed. She then got really condescending and said «we have never sold windows that low, you are talking about a competitor.» Funny because I was looking at that promo on their website as she was telling me this! I then asked her why she felt the need to be so rude on the phone and she quickly changed up her demeanor. I thanked her for her time and told her I am sure their competitor thanks her too because I am taking my business there.
Do not use Glass Block HQ! Go to a business that values you spending your hard earned money on their products. There are yahoo reviews that reference this same rude woman from 2013. She should be fired because she is costing them a lot of business!
Edit: found out from their competitor that the rude woman is the owner/​sales rep’s wife. Go figure.
