Downgrade seat

https://n.news.naver.com/article/421/0007023077?cds=news_edit

I made a reservation a month and a half in advance and reserved my seat in advance, but the airline said they didn't have a first class seat and couldn't give me a refund for downgrading to economy. If I didn't like my seat, I had to go on the next flight. Haha. I even booked two seats. How can they downgrade both of them? It was a moment when I thought I should study English harder because I couldn't do it. It was such an absurd experience, everyone, please be careful...

Is this natural English?

Your English is generally good, but it can be expressed in a more natural way. Here's how:

"I booked a first-class seat a month and a half in advance, even reserving my specific seat, but the airline informed me that there were no first-class seats available and refused to refund the difference when they downgraded me to economy. They offered me the option of taking a later flight if I wasn't satisfied with the new arrangement. I didn't understand, I had even booked two seats. How could they downgrade both? This experience made me realize I need to improve my English, as I struggled to argue my case. It was such a frustrating experience. Everyone, please be careful!"
