> I cannot believe you will get zero response.
Believe it. Our account seems to have been closed due to a KYC issue, and the bank, by law, cannot tell you any details. See this comment: https://news.ycombinator.com/item?id=41333832
And, yes: we tried every avenue to get more information, including having an attorney write a letter. As you can imagine, this was quite concerning for our company. We wanted to understand if there was some piece of information that might lead other banks to close our account. As I mentioned in another comment, none of our other accounts were closed - only this Chase account.
I tried again to get more information when the Chase accounts I opened, for another business and subsequently a personal credit card, were closed, although by that point, the only logical explanation was my connection to the business bank account that had previously been closed and I didn't have much hope that I'd get an answer.
Also: to be blunt I'm not sure what gave you the impression that I'm looking for advice. I was relating an old anecdote that was relevant to the OP, not asking for help. I just stay away from Chase. At this point I know that I'm blacklisted with them. I have no issue with other banks.
> What exactly is a "personal travel credit card"? I never heard that term before.
"Personal" as in: this was a credit card for me personally, not a business credit card. My point is that I seem to be blacklisted by Chase even for _personal_ accounts unconnected to the business whose account the closed. I assume you've heard of a "travel credit card", but if not: https://www.nerdwallet.com/best/credit-cards/travel
