(866) 808-7471 is an AT&T Rewards Scam

866-808-7471 is the number of a bona fide organization called Caremark, the drug company that services customers who obtain their drugs via the AARP Health Insurance system. The fact that someone used this number under the guise of "AT&T Direct TV" [see call reported above] strongly implies to me that scammers are routing their calls via this telephone number, i.e. they are spoofing.
