Dragon Nest Disappeared - how to contact customer service?

Does anyone know how to get in contact with customer service? The “contact us” just has pre asked questions! I’m looking for an email preferably. My dragon quest disappeared 2 days ago and I figured it would maybe come back once the event ended but it didn’t. I had one left to do and could have done it had it showed up for me! I really needed the prizes and I’m bummed all my hard work disappeared for nothing. Is there anything I can do?
