I once did on a school trip lol i complained beccause the room was clearly not clean, bathroom was disgusting. Hotel people didnt care, didnt listen. So i wrote a review on google and the hotel owner was ready to throw me out and even threatened to take me to court because I was "ruining is business" by writing bad reviews.

I did this to two different car dealerships. First dealership sold me a car that clearly had engine issues and pretended to "fix it" three times. They didn't have a certified technician for the make of my car so they had to send it elsewhere each time. After the third time they said after two weeks the check engine light would turn off. It didn't. Two years later I started having serious engine troubles so I called the dealership and they gave me the number of the place they sent it. They checked their records, they hadn't seen my car since a year before I bought it. I called the dealership back and they started back peddling about sending it out because they wouldn't do that, but then say they would do that because they don't have a technician for that...but they wouldn't send it out. Going in circles. Left a bad review and they called me asking me to change it. Nope

Second dealership I didn't even buy a car from. I went in during like a Thanksgiving sale and told them I wanted a RAV4. They didn't have any, but they did have some Tacomas so I test drove one. It wasn't bad, but I wasn't really feeling it and it was out of my price range so I kept saying no. They eventually went and got another sales person or two, sitting at a table literally in a corner trying to pressure me into buying the Tacoma saying it retains it's value more than a RAV4, they can lower the price but raise the interest, blah blah blah. After about 15 minutes I said I'm done, I'm absolutely not buying a vehicle from them now after this. A month later I left a bad review explaining all this, and somehow THEY CALLED ME even though I never left a number. Not sure how tf they got my number, but they called me demanding I change the review but I had just had a terrible day at work and refused.

Never threatened to get sued, but car dealerships don't fuck around with bad reviews
