This call sounds like a well done scam. However, it is very unusual for scammers to retain a static caller id such as 423-822-2465 in Chattanooga TN.
Caller name: CVS CareMark
Caller type: Appointment Reminder
Just found The Rest Of The Story. The number belongs to CVS CareMark who performs many tasks for Silverscript, the insurance arm of CVS. Due to my Medicare Part D insurance they got my list of prescriptions from *Costco* for monitoring.
The ACD system at the above number stated that one of mine was overdue for refill - not a bad service but I don't really need it.
NOT A SCAM !!
