Looks like I found my answer, but it was burried realy deep
The search function in Help is terrible.. When you write refund it only finds something about Tax refunds. When you write Cancel, Canceled, canceling it only finds how to cancel Acuity payment subscription plan.
If anyone else is wondering regarding this topic
Somewhere and somehow i found this.. but i can' t find this anymore
