Note the timing. What’s the statute of limitations for civil actions in Washington? If it’s one year, I suspect a strong letter and a media campaign (as is obviously going on) is probably the only approach that’d be effective.
If he’s still within the Washington statute, that “letter” was probably a demand letter. The fact that he got a response from their PR department instead of the legal department makes me think the first situation’s probably it. In that case, they’ll most likely pay him to go away.
It's three years. Lawyer is taking a "be nice approach" in getting a settlement. When Chase blows it off, the real lawsuit will begin and the lawyer can tell a jury that his client tried to be reasonable and Chase just ignored a little guy. What better way than that to get a jury to make a big award?
Fraud 3yr, libel or slander 2yr.
