This is the voicemail I received...

"This is Michael Giardino from the DEA - Drug Enforcement Agency wishing to speak to a [insert first/last name] about an investigation. Please call us back immediately at 443-288-3117. Thank you."

443-288-3117 is a LANDLINE number in Ellicott City, Maryland (NEAR, but not actually IN the Baltimore metro area where the field office is located).  The following is the REAL Baltimore District Office address and phone number...

Baltimore District Office
200 St. Paul Plaza, Suite 2222
Baltimore, Maryland 21202
(410) 962-4800

The real DEA would never call your home. Rather, they would coordinate with local police and other authorities to reach you. Furthermore, a DEA agent would not call FROM his/her residence either (in regard to the possibility that the agent's residence was in Ellicott City, MD).

Same type of message "from the DA".  He said to call back immediately.  He had a strong sloppy accent and hacked my last name.  Sounds like a guy who keeps bugging me to buy prescription drugs.  Total loser.

I recieved the same message from 443-288-3117 . . . same guy - thanks for the information. The call came minutes after a similar voice called to sell  perscriptions? I think it's the same guy. He once asked to send him money via western union! He is not with the DEA !

This is a person that threatens you too (from Ellicott City), somehow they call you and hope to scam you or just to be mean;  then when you posture they go nuts, and accuse you - - no professional would ever treat you like a thug!  complete loser to do that to people,,, no heart - only animal ways, complete gutter rat, I mean who would cus and threaten you, ....it would have to be a completely a person that is hurting very badly in life and wants to ruin yours with stealing on your credit card, stand up to these idiots always!   They should not do that to people but they really try and it is very SICK!!!!     People like this are most of the problems in the world,, in my opinion,,,  this is the type of person that would hold you up at an ATM with a weapon of sorts, fight back and report them!!!  and be happy for each day that you don't have people like that - god what garbage!!!   ...just think in a 100 years this person will be gone for sure... yea!!!

I got a call from this joker too.  He called twice while I was showering...  When I checked messages, I listened to our man with "crackly" reception.  Said he was DEA working on a case, yes I have had a lot of these type of calls since I did use an online pharmacy so clearly my contact info was sold....  In any case,  I blocked my phone number and called back, some lethargic lady answered; "DEA how may I direct your call?"
I responded with do you have an agent "Mike Giardino" working out of this site?  Lady said who is calling?  This is of no concern to you but I'd like to warn you that I have made a formal and technical complaint to the FCC regarding you and your companion using a call list to scare and potentially extort from people while impersonating a Federal agent.  Your "Magic Jack" has forwarded the IP address from the ISP and has Identified your location as well as identity of account holder so please be advised you are now on the receiving end of your intentions however this is very much a reality.
Good luck with all of it
