2 months ago I signed up for a 30 day trial to search for people to hire and then 140 eu/mo if I decide to continue using it. Of course I forgot to stop it (they were pretty quiet also) and they charged me 1400+ eu for a full year because...why not - no refunds (that's what their page says). I know, I know...should have read the whole shebang. Lost 1400 euros for something I didn't really use. I was about to pay for…
You should file a complaint with you consumer protection agency. And ask you bank to cancel the payment, just call it fraud.
I know, it's easy to feel like you were being stupid. But they are intentionally preying in you, it's not by accident, it's by design. That IMO makes it fraud, fight back.
