LAX - DCA

I booked my flight through Kayak, a third-party website, and paid extra for reserved seating. A few days before our trip, Alaska Airlines emailed to let me know that it had changed our reserved seats and separated us. I was traveling with my son who has a disability and we needed seats next to each other. So, I called Alaska and talked to an agent but she refused to give our seats back together. She blamed me for buying my tickets through a third party and said that this wouldn't have happened if I brought directly from Alaska Airlines. I was appalled by the agent's lack of empathy and ignorance of what my son's disability entails. Even though I tried explaining to her that one of the manifestations of my son's disability is high anxiety and that anxiety sky-rockets when he's in crowded places or is taken out of his routines, she just could not care less.
