Complaint Review: Express Flooring

DO NOT BUY FROM EXPRESS FLOORING!!!! 
My husband wanted a quote from them...I didn't after reading their bad reviews. The sales manager came, gave us the sales pitch..I had my doubts about the density & quality, but he promised the carpet was newest technology in manufacturing, and the twist would hold...and has a 30 year warranty if it didn't!! 
Well...that sold us and the fact that they would come the next day and install!! 
Install went fine...it looked great...for about a month!!
I called them about 10 weeks later because the traffic area in bedroom was matting already and as soon as you vacuumed and stepped on it a few times...it was flattened! 
They send one of their own guys to come and look at it, ( I do not think he liked what he saw) then a month later they sent someone from the manufacturing company to look at it.
He did his little test of raking a 18 sq. inch area and took a picture ...no compression at all! (he should have taking another picture once it was stepped on a few times!) Then he sent in his report that my carpet was just fine!!
I've shown pictures of my carpet to Customer Service Manager; Henry and have talked and emailed with Henry many times. He says I should be vacuuming my carpet every couple of days and I could rake it every day!! He also says, that these are not our products, we do not make them! 
So, I wonder why they sell such inferior products?? 
I really feel I was misrepresented by their products and policies!

Express Flooring is prepared to give me the installation free if I buy more carpet from them! That is not going to happen...

I will not trust them again!
