I have received numerous calls from this number, no one has ever left a voicemail. I returned the call and the message said this is a courtesy call. If you have any questions call 1800REGIONS.
The person did not sound at all professional. He said he was with Regions Bank, but then asked me what features of the bank I used such as credit cards, bank card, etc. I suspected fraud and informed him that I was terminating the conversation.
