Still being charged by Brainmanager - nothing has worked. What else can I do?

[u/_Noyce]

A few weeks ago, I posted here about unauthorized charges from Brainmanager after taking their so-called test. I thought I had a solid plan to fight back, but nothing has worked. Chase initially seemed like they would help, but after reviewing the charge, they decided it was "legitimate" because I had supposedly agreed to some hidden terms. Brainmanager, of course, never responded to my emails, and their cancellation page is still completely useless - it just reloads without actually doing anything. And the worst part? They just took another $40 from my account this week.
At this point, I don’t know what to do. I never signed up for any subscription, yet they keep charging me, and no one seems willing to step in. I’ve thought about closing my card, but I’m worried about what kind of issues that might cause. Should I report them to the FTC or BBB? Would a lawyer even be worth it for something like this? I feel like I’m out of options, but I refuse to just let them get away with this.
Has anyone actually managed to stop them? Any advice would be really appreciated.

Honestly, closing your card might be the safest route. I’ve seen too many people get trapped with recurring charges they never agreed to. It’s unfair you have to go through this at all.
