Wording and phrasing on the letter is suspect. Don’t think JPM Chase corporate would say anything like “We are closing your credit cards”. That’s clumsy Middle Eastern sentence speak. You don’t “close” a credit card. You “close” an account. I call BS as this letter looks like a set-up or a scam. Written by someone who has ESL. Not from Chase corporate.
Re: 21 - Good catch. The wording used is incorrect.
FAKE NEWS.
