First called as "Robert Williams". Then we spoke to "Matthew Barnes" DEA # 77936. Said he needed over $1700 to make the arrest warrant go away. Wanted us to go to a Western Union in a CVS Pharmacy. It all sounded fishy & when we questioned him for supporting evidence he got very angry & talked about how he's been on the force for 17 years & they would come arrest us within 25 minutes. However, he said no local  law enforcement agency would have the case number or any record of this.
We called the FBI!

I got the same call - he is a fake and - I reported him to the actual feds and they are going to put him away for presenting himself as a federal official.

Yes, I got the same message from "Agent Barnes" requesting payment of a fine for ordering a prescription from out of the country.

Pretending to be Special Agent Matthew Barnes from DEA.
