It was a robocall from 415-894-0917 claiming to be from CVS Caremark telling me to call 866-231-9923 and give a 7 digit number so they could help me 'manage my prescriptions.' I do get prescriptions from them but they called to a number that is not in my contact information there - I double checked to make sure.
I also received a call from 415-894-0917 saying they were from CVS caremark not sure if it's a spoof but it doesn't come up in caller id except the phone number
