Wow! This is exactly what I have been saying, buying from a online only company crossing state lines can become a consumers financial nightmare with a implied warranty. You can file a complaint with your states Attorney generals office but make sure You have all paper work in order first. Photos everything before you do they will ask for proof of purchase. I had a issue with a speaker company back in 2018 but was no wheres near as bad as your issue mine was just speaker wire connectors on new tower speakers I got feed up dealing with their dumb a$$ marketing manager so I and my son just replaced all of the wire connectors. I sent in a complaint to my states attorney office, sent everything photos pics of the wrongs size connectors even one recorded phone call between me and their marketing manager. Took about 3 weeks before I heard back was told that I would have to file a complaint in the state that the speakers where sold from. Best of luck man. look like you got the run around treatment like I did.
