Cactus Construction and Remodeling

I paid $ 50,000 so far for a 380 sq ft trailer remodel with a design plan provided on CAD by my designer. My drywall has already started to crack in many places. Cactus claimed to be a trailer specialist, but when I had cracks, he said it was because it was a trailer. BTW, the cracks were in the brand new middle wall THEY built. He told me his «drywallers screwed me over». As a business owner, one needs to take responsibility for their subs. I owned my own business for 18 years and the owner is the bottom line and takes all responsibility. It rained hard last night and I now have leaks around my electrical outlets (ow!) and my cat door. Woke up to a huge puddle inside my house in my one month old remodeled trailer. There were gaps left around almost everything (including my ceiling lights, toilet flusher, vanity mirror, outside window) and when I mentioned it, they just squirted caulking EVERYWHERE! His wife came out with him and told me my expectations were too high. Really? You are welcome to request photos or come by for a tour so that you don’t make the same mistake I did.
btw, of course they were behind schedule after having to reframe the closet three times with a drawing provided.
They have come back several times and are just not capable of repairing/​fixing the problems. They are now asking for final payment of $ 2000.00 stating the job is done. They damaged my custom built cabinetry and gave me a credit of $ 1,300 which covers the materials only.
I have a perfect credit score btw and always pay my bills. I am a professional woman and feel that this company has taken advantage of me severely. I have not seen any reviews and that may be because they cater to the retired community who may not be online. This was the remainder of my savings and I am sure others have, unfortunately, experienced the same.
