Can I resell tickets that I have bought on Eventfrog or other platforms on Eventfrog?

Clear answer: No.

Only event organisers are allowed to sell tickets for their own events on Eventfrog.
The resale of tickets that you have purchased - whether on Eventfrog or elsewhere - is not permitted on our platform.

What you can do instead:

Contact the event organiser from whom you purchased your ticket directly. 
In many cases, you can request a cancellation or refund there. However, the event organiser alone decides whether and how this works.
