Whenever I move significant sums into my bank account, I guarantee that my bank is going to do an "Alex" call. I can also guarantee that there is no freaking way I am going to do a call with some rando not already in my contacts to discuss my financials. I really don't know why banks don't understand this.
Chase is not the only offender but they are unhilariously, shockingly bad at this: if you do a large transfer, they will sometimes cancel it unilaterally and without warning because of their fraud detection. And then they'll call you, but the dude speaking won't know anything about your account and ask you about what you just did. "We are clean on opsec" is very much not the vibe.
Lest this be just me moaning, Fidelity gets it right. When you log on you can see who your banker is and how to reach them. A real human with a phone! And that person is the one who calls you, emails you, and you can set up a call/mtg with, so you don't have these random calling you.
