This guy was only saved because he saved the screenshots.
This may seem like overkill, but whenever I'm dealing with customer service for a significant financial concern, I always take detailed notes: time, date, name, what was discussed, and screenshots when relevant.
Just a few years ago a large appliance company tried to dick me around on a faulty product that was several thousand dollars.
It took weeks of back and forth, but when I was able to make contact with a layer of management just outside and above their customer service channel with my very long and detailed log of their bullshit, they authorized a check the next day.
