Negative reviews are always gonna pop out. It's part of business and life. But what do yu do about reviews that bordered on derogatory? Insulting remarks? What is the best step to do? Ignore it? Or answer it?
If you answer it, the problem might escalate specially if the person is doing it on purpose. if you ignore it, the person might think you are easy to bully and it will also make you look bad in public. Where do you stand?
