Look, you can do what you want.... If you were in her situation and decided to spend all this time to "prove a point" then more power to you.
This kinda shit is going to happen to everyone at some point in thier life. When it happens to you by all means make a huge stink, file lawsuits, prove all the points you want.
If this were me, I would take the 4 grand and move on with my life.
Seriosly dude, when this kinda thing happens to you, AND IT WILL SOMEDAY, and your going to take this kinda thing as a "personal insult" then your going to spend your entire life being insulted by companies.
Wait untill you have insurance to manage, different student loans to take care, 3 different banks for loans... car payments, house payments. Kids daycare payments.
At some point they ALL are gonna fuck something up, and youll have to take action.
But by all means, sue them all for billions of dollars. Because you were "insulted".
