The only choice that doesn't route me to the CFPB is: >The company asked me to pay a fee before they would issue me credit.
You never did receive what you ordered: a working product.
One time, I just had to tell a company while I was on the phone with them, that I had this specific website open on my computer and was filling out the form. That got them to resolve the issue immediately.
Unfortunately, this would only address the issue with Newegg, not Chase. But you should still get your refund, or the monitor, which you can then return for a refund (if you ended up buying another one somewhere else already). If Newegg says it's too late for a refund, tell them to read their own ToS which says you are elligible for a refund, or that you will sue them in small claims court. Or you could use your credit card's warrenty if it has one.
Heck, if your credit card has warranty coverage, did you try using that? From what I understand, if you try returning a defective item and the store won't accept it, the credit card company will just write you a check.
Just open a new case with the credit card company and don't refer to the old issue/case.
