Have you ever written a negative review about a company online?

I have never had such a situation, because when I receive bad service or any trouble happens, I try to solve it with the managers, so there is no need to write a bad review, but if it happens with some online services and your support does not understand and protect the employee even if he is guilty and you just can't do anything to them because you won't make them return the money. The only option is to write a bad review if there is such an opportunity, but it will not always help to solve the problem because it can be deleted. Have you ever done this?
