Then Chase will know you are serious.
This is likely bad advice. The moment you threaten legal action to a large corporation, your case is transferred to the legal team and every single front line (and not-so-front line) employee is prohibited from communicating with you. If you want to shut down all lines of communications and only deal with their legal team, do what garykung suggests.
