@glitzersachen @CaptainJanegay @Extelec @Edent I don't think it's that obvious at all. It's a real notification from the bank. They still shouldn't be calling you like that but people do that.
Making them let you call them is the right decision, though. With the said, calling the front of the bank probably won't work for Chase. Not unless your bank account has a couple more zeros in it than mine does and if that's the case you probably have your own concierge line or something like that.
