If you receive an ambiguous call or message mail from an unknown number, you can try calling them back and ask for their identity. Never call back a potentially swindle number. You can search up their number on a search engine. If they have connected the number to any social media, it will be shown on the top search.
You can then use their social media profile to identify them. If the scammer repeatedly asks for money, we recommend going to the police and asking them for help. You can also take legal action against the person calling or sending you text emails.
