Cheaptickets, retourvlucht niet vergoed

Heb bij Cheaptickets retourvlucht Eindhoven - Krakau geboekt. Transavia annuleert deze heenvlucht en belooft mij terug te betalen (nog geen geld ontvangen) Terugvlucht van Krakau naar Eindhoven is met Raynair. Raynair geeft geen geld terug want zij zeggen dat ik de terugvlucht kan maken. Heb Cheaptickets gemaild omdat ik daar mijn retourvlucht heb geboekt maar dan krijg ik als antwoord:

Schedule changes are always made by the airline, not by us. The airline is responsible for the transportation of the client to the destination which the client has originally purchased. However, airlines have the right to make changes to the flight schedule at any time.

Although schedule changes are made by the airline, we do our best to help you in the 'processing' of your schedule change. Such modifications always require a follow-up. It is never possible to maintain your original flight.
Since you are flying with a low-cost airline, you have to contact them directly to make any changes, cancellations, or refunds. We don't have access to their booking system. Though you have booked the reservation using our website the airline is a low-cost carrier due to which we cannot assist you.

Mijn verlies nemen? Graag advies wat ik moet ondernemen en bij wie. Raynair doet helemaal niets voor mij. Heb ik nog rechten?
