Some of what was said in the tweets regarding your rights and what you have to do to file a claim are, in my experience and opinion, not correct.
The general idea is right, but some of the asides about the law were simply incorrect.
Depending on your jurisdiction, the way you can pursue a case like this is going to vary, so I’m not going to give any hard and fast rules in this comment.
Just a heads up that if you want to try to replicate this, your steps will probably be different.
Not legal advice :)
