Kustom Window and Door Sierra Interior I found this company on Thumbtack.com. They had fake reviews, all of which were positive, that led me to believe this was a wonderful company to hire. David Chong is a fake and came to my house to take measurements and asked for a deposit, which I gave via check. I have not heard from him since and every review on Thumbtack says that he is a fake.

I went onto Thumbtack.com to find someone to install new windows and doors in my house. A company by the name of Kustom Window and Door, aka Sierra Interior, answered my request and agreed to do the work for much less than any other company, due to the fact that he orders doors and windows in bulk for large jobs. It sounded legit so I had David Lee Chong come to the house to take measurements and give him a deposit. I have not heard from him since and the entire page on Thumbtack is lit up with SCAM notifications. He is a fraud. He only takes checks and Thumbtack needs to be held accountable.
