I would like to receive legal advice on what can be done against an online fraudster in a certain scenario?

One person agrees to exchange money with another person for a code that can be used on the Internet. One person gives the money to the other on condition that the person opposite is aware that he is then giving the working code to the creditor. However, she takes the money and gives out a code that has already been used and tries to avoid any contact. The entire process is recorded on record. I would be happy if someone could tell me the rights with which the creditor could get the money back or get an active code. Both people live in Germany, only that the seller hides behind a Twitter / Twitch / Steam account. "It's only about one scenario. I'm aware that a lawyer / the police would be the next point of contact in reality"

Your own fault.

Very simple fraud, will be reported to the police.

A lawyer can give you the most helpful answer. I don't think you can find one here.

You can track the IP and so when you go to the police with it you can find out the address and name of the person ka whether that helps you can ask if you do not understand something.

How exactly?

Of course there are some here

You can enter ip tracking at yt or look on the internet. You can send a link to the person you want to track and if he presses it, his ip will be displayed

You can hire a lawyer to do this, who will then invoice you for his work in the form of an hourly fee.

Legal protection insurance only gives you coverage in a specific case.
