Yes, this is Chase. I told them I would call back, and indeed, after calling the number on back of my Credit Card, they verified that they had called asking about an issue with my Chase credit card. So, it is legitimate...but, the scammers can now spoof numbers, so I would always call back
Please file a complaint with the FCC for each and every call you get. These people are NOT CHASE - no matter what they say. You can call Chase directly and give them the number and they will tell you that these types of calls are SCAMMERS trying to get your personal information. Please go to www.FCC.GOV and file a complaint right on line. It is the only way to stop them. The more complaints the FCC gets the more pressure they have to find these creeps.
