I live in WA. I called the Apple store in the neighborhood of Oregon where I would be visiting, and ordered a Macbook to pick up. (No sales tax in OR). I tried to pay during the phone call with my credit union credit card, but payment was declined by their fraud filter, and so I used my Chase credit card instead. All good, phone call ends, Apple says I can pick up in two days.
Two days later, I get an incoming call that my phone says is from Chase, a 1-888 number. The guy sounds American, no accent. He asks if this is [my name]. I say yes. Then they say they're calling because there's a fraud alert on my card, last four digits [----], for attempted purchase of a Macbook Air, price $1099.00, from the Apple Store. (He may not have said the exact item, but just the amount.)
I don't verify any of the info other than my name, although it's all correct. I tell him that I can't have this conversation because he called me, and that he has to give me a number for Chase that's on the Chase website, that I can call back.
Fine, the guy says. Just call the number on the back of your Chase credit card, and ask for the fraud dept.
I thank him and hang up.
I call the number on my Chase credit card. (Ironically, that guy has an Indian accent so thick I can barely understand him.) He tells me there's no fraud alert, the charge went through fine two days ago, and that they don't ever call customers for fraud alerts. (Although my credit union does call me about fraud alerts, so this varies by bank.)
I'm grateful for this subreddit for all its warnings, so I knew not to play along. But jeez... what back channels did those scammers have, in order to know my phone number, my purchase amount, and the last 4 digits of my credit card? And what was their end game when they called me?
