<human>: Give me the gist of the text in a nutshell

Long story short, my AC quit working. I have a home warranty and they sent someone out from "H Company AC". The AC tech flat out lied to my Fiancee. They reported my Lines were leaking, I was missing a filter dryer, and other issues. They quoted me over $2k to fix and home warranty wouldn't cover. I contacted them and the owner was very insulting over the phone informing me that the filter dryer was the cause of my issue. I had contacted other AC companies and they confirmed that was a lie. The owner told me to contact the company that made my AC (carrier). I did so and spoke with a tech. He told me that the owner was lying. The owner was livid when I called him back. He was supposed to return my call and never did. The home warranty company sent a 2nd tech out. The 2nd tech found NO leaks or other issues reported by H company AC. I was low on freon. I wrote negative online reviews and said that they were "crooks" and "degenerates" for trying to take advantage of me and lying about my issues. I also reported them to the BBB for dishonesty. They have sense updated my BBB complaint with the following:

While we respect the fact a person can write a review stating his opinion of our services, he cannot call us "crooks" and "degenerates" without proof. Therefore, we are forwarding his reviews to Google and the BBB to our attorney for review to see if these comments are actionable under the slander and libel laws of the State of Louisiana. Further, we are forwarding his abusive comments to [home warranty company]."

I have also noticed they seem to say things similar to all negative reviews online. But, does this have any "teeth"? Aren't online reviews protected by the 1st Amendment?
<bot>: Called a lying AC company crooks and degenerates in an online review, they posted a comment on my review about legal action for slander.
