Some things are wrong but there is no practical legal remedy. Best to move on.
This is not legal advice. You should always discuss the specifics of your issue in person with an attorney. Be aware that there are time limits on all claims that depend on the kind of claim, so do not delay in seeking an attorney.
To put it in laymen's terms, you've got nothing. Zip. Nada. No breach of contract. No negligence. No damages. Its is never a good idea to mouth off to airline personnel these days, whether you have a right to or not.
DISCLAIMER: This is not specific legal advice and does not establish an attorney/client relationship.
