Hi hedda83,
welcome to the Apple (user-to-user) Community!
Re: "I get charget money and i dont know ehy because i dont have any abonoments (subscriptions) active and didnt buy anything: : "It has happened before and i tried to change my card but it still gets charged".
If the charges are from Apple, you can see what you were charged for by following the article below:
If you see 'apple.com/bill' on your billing statement - Apple Support
Eg: says:
How to see what you (or a family member) were charged for:
- To see your purchase history, go to reportaproblem.apple.com.
- Sign in with your Apple ID.
- A list of purchases appears. To see family members' purchases, select the Apple ID button and choose a family member.
- To see the full receipt including tax, tap or click the date.
- Multiple purchases, including subscriptions, might be grouped onto one charge.
If needed: Find out where else you can view your Purchase History.
If you still can't find what you were charged for see that first linked article for tips on checking for a receipt
If you checked reportaproblem.apple.com and your emailed receipts and you're still not sure why you were charged, contact Apple Support.

If you find the charge is for a subscription «abonomang» that you do not want:
See if you can cancel the subscription so you won't be charged again,
and then you may want to ask Apple for a refund:
What to do: If you want to cancel a subscription from Apple - Apple Support
and
How to: Request a refund for apps or content that you bought from Apple - Apple Support
All the best :-)
