Chase just closed my CC (Fairmont Visa), again. Opened single CC after last shutdown, met spending requirement very slow (very little MS). Paid my bills using linked checking account. I have no idea what went wrong. My only suggestion is due to small disputed charge I submitted with one merchant.
Was your first shutdown due to MS? I agree that getting eyes on your account post shutdown is what got you shutdown this time. After all of that, did the dispute even get resolved? They should still resolve the issue since you had a valid credit card account when you filed it. If not, cfpb them.
