Said they were the DEA and said they needed to speak to "Mr Stewart" about his drug activity.
Too much info left on a voicemail to be legit. I feel this is SPAM.

Its more like Extortion Scam..

Received a call from this number a few days ago...same thing from above...DEA blah blah blah about illegal actviity.  DEFINITELY sounds like a scam of some sort.  Message was almost 2:00 long.  Someone please look into this!

Got the same call from the guy who claimed to be law enforcement. Thanks for posting this online

Received voicemail call as described in above posts, "illegal drug sales regarding Gaylord Pharmaceutical", etc. Agt. Ryan Harris, Agt. 294, said I was main buyer?  Very scripted. I called BBB but they had had no complaints here. Hope this is looked into. White Pages list the number as coming from YMax Communications Corp., landline. Placenta, CA. Did NOT call back.
