don't worry about this 3 day nonsense. Nobody works that fast. This was a red flag for me too. 3 days to take action? It takes longer than that to get anything done these days. They're trying to scare you into compliance. Three days is not enough time to get legal advice from an actual lawyer who is versed in domain name law, and respond. If you're gonna spend any money with a lawyer, have one write up a "go away or I'll let this go to trial and you can pay my legal fees" letter to send back to them.
