My neighbor’s shop is charging customers unfairly. Can I use their shop name (not their logo) on my website to tell people they can check if they’re being charged correctly? Would that be illegal? I just want to help customers get a fair deal. How can I do this right?

Using your neighbor’s shop name on your website to warn customers about unfair pricing could be considered defamation, even if your intention is to help. You could face legal action if your statements are false or misleading. The best way to help customers is to report the unfair pricing to consumer protection authorities.
