Received an automated call from this number. Upon answering, the message said, this is Express Scripts calling for [they said my full name]. Then the automated message said, "YES" or "NO". I responded "YES" since Express Scripts is my mail order prescription company. However, as soon as I responded YES, the phone hung up. I called the number back and an automated messaged immediately came on stating that I should have received a packet with information about new prescription benefits and they wanted to make sure I read the information. Then the phone hung up again. I did get a packet from Express Scripts about one week ago regarding new prescription coverages.  However, the request to reply YES or NO was odd and suspicious. Not sure if it was really Express Scripts.
