My name is Yoon-Kyung Kim, and I am a presenter at the DRUID 2023 conference. 

I am writing to inquire about the refund of the registration fee.

Unfortunately, I did not know the registration fee includes dinner, so I checked the dinner option (100 euros).

Since I am receiving school funding for DRUID 2023, I need to get a revised receipt as soon as possible.

I would like your assistance in finding a solution for my refund. 

Thank you for your attention to this matter, and I look forward to your response.

Best regards, 

Yoon-Kyung Kim
