Question Why I have been charged by Unity for something that I don't know?

Hello, first of all please excuse me if this is not the right place to post my question, but I was not able to find another place for it. This is why I'm posting this message in so many places.
An it's so f*** urgent!
If you can tell the right place for my question (somewhere to get in touch with Unity commercial) I'll be happy to post it in the right place.
I've just been charged by Unity for something that I don't know (17€)
Ok, the price is not so high, but... for what?
In my Asset Store I can't see any subscription (I didn't do any subscription indeed), and I didn't subscribed to the any of the Unity platform (pro or enterprise).
Moreover, in my account the credit card that I've been charged for is not listed...
Maybe someone stole my card, and it is making transaction with it ??
This is the report from my bank account:
UNITY COPENAGHEN DK 5478392705872276 17.87 EUR 08:08 220528
Any help would be much appreciated!
Thank-you
