Can contractor sue for leaving bad review online?

[Page Trip]

Hello,

Recently I found some contractors on Thumbtack and asked them for a quote. I had about 8-9 different contractors visit my home to give me a quote. One of the contractors clearly took advantage of me not knowing anything about roof fixing and gave me a quote of $1000 for something that costs $100-$150. Every other contractor confirmed it too. The $1000 quote they gave was to put silicone around 9 nails on the roof.

I wrote a review stating the same. Also mentioned that if someone is looking to hire them then they should get a second opinion. Initially he tried to call me and threatened saying that they have my address. When I stopped taking their calls he sent me an SMS asking me to take down the reviews or they will sue me with defamation. The text also said something to the extent of "we have your address".

No where in my review I stated that I hired them. I only said that their intentions seemed to take advantage of my ignorance in roof repairing matters and it seemed that they were out to cheat me.

I definitely don't want to deal with lawyers for such a trivial issue. I can delete the review but what is the point of reviews if we can't leave negative reviews? Can a business really sue someone for writing a negative review?

P.S.: The name of the business is Exteriors Dr (in case I end up deleting the review).

P.P.S.: I would genuinely like to know if my review (or any part of review) is defaming the company. If yes, then I can edit the review without going into specifics.
