American Airlines Canceled Flight Problems

Me and my husband was supposed to go to San Jose on 9 August. AA called us and said our flight is cancelled and we have to go next day. We had to go same day as it was urgent so we called them. AA put us not to direct flight to San Jose but we had to change two times our plane from Washington to Texas first then to Denver and then to Oakland. We reached midnight to Oakland. The airlines did not apologize to us and gave us any discount. We are not going to go by that airline anymore we decided.Even in plane our seats were not next to each other.
