Edreams not responsive in refunding flight bookings

Im not getting any feedback regarding flight refunds from Edreams. Bookings were made for kulula and flysafair.. Flysafair had deposited my refund into Edreams account. My kulula flight cant be refunded. I cant get hold of anyone as this is an international company. Why do they assist in bookings if they cant help with enquiries. Theres no way of getting any reaction from Edreams
