Some idiot saying he is with the DEA or FDA.

Do not fall for this nonsense. It is a shakedown. I have had calls from the same guy saying he is FDA, DEA and has a supoena for me. If you go to FDA sight and do a search you will see they are scammers. Pass it on.

Heavy accent.  Claimed to be from "PDC" asking if I need a refill on phentermine - which I have never in my life taken!

They have been calling me about 6 or 7 times a year for the last four years. They used to ask for a specific name and say they were from a pharmacy or ask if I was a pharmacy. They some kind of African continent accent. I figure they have me on some list they review to correct. Now when I tell them to stop calling they will sometimes get beligerant or tell me they are Drug Enforcment Agents. I think I need to contact the feds about them

I told the guy on the phone to [***] Off and he immediately got upset and started cursing at me. Now that doesn't sound like a real DEA or whatever the [***] this guy is. I got a call from this moron  last year and did the same thing. I actually called the FBI and was trying to get this number traced and stopped.
