That's ridiculous..."I'm going to email Oscar about this". Good luck with that.

You got $200 back and you're now flying first class. Yet you complain.

As you know, all airlines use dynamic pricing models. They are free to charge what they want when they want. If they want to lower the fare the next day after you purchase that's their right. And it's also their right not to notify you or anyone else that the price dropped. It's up to the purchaser/flyer to check.

Lucky for you, you found a lower fare and were able to get an even lower one calling the agent. I'm not sure if you are saving your employer money or yourself money but it doesn't really matter. You got the cabin you wanted and got a refund in the meantime. Enjoy it.

So, yes, please contact Oscar and tell him, "I don't like that you lowered the fare and gave me money back and gave me a first class seat. I prefer you only keep increasing fares as the date of travel gets closer so I can feel like I got the best deal." That's basically what I'm getting out of your post.
