I have never seen an Attorney General take action on a consumer complaint. The best outcome I’ve seen is they make the complaint public record, then do nothing. Other AGs reply to say “not a violation of deceptive trade practices”. And some AGs do not respond at all - they just ignore complaints.
The FTC and CFPB are also options but those are also often deadbeat agencies particularly under republican governance.
What’s the recourse? Who generally oversees a state’s AG?

im unfamiliar with AG behavior outside absolutely craven, depraved corruption
A lawyer once told me there are a few left-leaning AGs who genuinely take the consumer protection role seriously. He named off a few states where he said you can expect decent treatment of compaints. Then he said a lot of AGs have no interest in the job at all. That they are just looking to climb the ladder and get a CV that enables them to run for governor. I think I have been quite unlucky with the states that are relevant to where I get burnt as a consumer. Though I don’t suppose that’s chance. The shittiest corporations are likely to select right-leaning anti-consumer states for their HQ.
