Who called from 9787731331

I've received called a couple of times before.  This is Express Scripts Pharmacy calling about one of my mail order prescriptions.  It is an automated recording, but it's legit.

Another Express Scripts number.  Returning the call will bring on the auto attendant with a basket of useless options.

This is a legitimate number- ExpressScripts. They called me about an issue with one of my rxs. Nothing else.
