Interesting story that’s sadly too representative of the gross incompetence and negligence of some companies. In scenarios like this absolutely do sue them and then deny every settlement offer their corporate lawyers throw at you, continually demanding a jury trial. After a few failed attempts to get the case thrown out on technicalities they will start freaking out knowing they don’t stand a chance in front of a jury and will offer up very very generous settlements to compensate you for their incompetence.
