This is Jp morgan/chase bank. All calls coming from that building come up 302-758-1000 no matter if it is card sevice,fraud,or whatever...My husband works in that building as a software engineer and if he calls from his desk phone it comes up the same.
I received a phone call requesting an update to my credit card information. I have never received a call like that from my company and when I told the guy I was wary about scams and ask him to explain a bit more he had nothing to say and just responded, Ok, thank you for your time. Sounded quite normal and professional and I could see how some folks might provide their information to him.
got a call from a very professional sounding woman asking for sensitive financial information so that my bank could update my credit profile. I asked what bank and she could not answer that. I let her know that was information that people just don't give up over the phone to non verified callers. I called my bank and they had no notes about needing information to update our credit cards.
