This is legit. Recd a call from this number while i was at the movies. I checked this number on the internet and found messages confirming that it was Chase phone number. I immediately checked my chase credit card a/c online and found three fraudulent pending charges charged to my a/c in the last three hours.
I just took a call fromt he same number. It was thefraud prevention department of Chase. I made a $ 2600 online purchase and they called to verify it was no fraud. They asked for no CC# or anything like, the call was legit.
