eDreams Flight Cancellation And Non-Refund System Is Crooked

I have made a flight cancellation on the Edreams web site I cancelled my flight for some reasons. Edreams has informed me that there was no refund related with my flight. I can accept non refund about cancellation but will they not rebook my seat cancelled?Imagine most of people cancel reservation and the plane departs without passengers! I suggest to Edreams and flight company represantatives that this is a fraud of stealing money from passengers without their permission. the answer of Edreams is below: " Dear Alaettin S*****, With regard to your booking reference 13592200747 with eDreams Thank you for contacting us about your flight cancellation. We confirm that it has been cancelled on your behalf. Unfortunately, your booking is not refundable based on the terms and conditions. Therefore, you are not entitled for a refund. Once again, thank you for choosing eDreams, we look forward to being of service to you in the future. Kind regards, Your eDreams Customer Services Team "
