How to use Mint when Visa requires upgrade of browser to old Macs?

Dear A.I. or any available human,

Your human, a chat person named Tomer just exited the chat because I asked it the above subject line question. How do I get around the upgrade requirement of my credit card Visa that I change my Mojave (Safari) browser since I no longer would be able to accomplish this?

Please comment to this name at aol or reply to this question.
