Possible scam call.
Scammer trying to get personal information.
Fifth Third Bank doesn't have 800-837-5745. It's a scam.
They claim to be 5/3 if you get a voicemail message. I called 5/3 and spoke to a banker as I don’t recognize this as any of 5/3’s numbers, and sure enough I was told that this is an unfamiliar number to even the banker to whom I spoke and was advised to not answer or, if I do, not give any info. It is NOT 5/3.
