If you have a net worth of a few hundred thousand dollars you can engage in "private banking" services with many major banks. You will be paired with a banker who can work as your advocate, bend internal rules, and cut down the amount of time required to deal with disputes. If your card happens to be issued by that bank, I would imagine they could assist with aspects of that.

If you have substantially more money than that then you can enlist financial professionals to legally act on your behalf and settle disputes for you.
