Unexpected Charge for Relume Subscription: Need Help Resolving It

Hello! My team and I got the free version of relume and I was under the impression that it would cancel automatically after 1 month, but it charged us $480.00 (pic below gave me the impression it was 40/month with a one time yearly pay). Can someone please help me on this? I would love a little time to to tinker with it more with my team if that's possible, if not, can I please cancel the subscription?
