Call the 1-877 number to report the scam.

My wife received a scammed call this week. we have never bought drugs over the internet so I researched the number and got to here. Thanks for all the posts.

Claiming to be DEA Agent Matthew Barnes, Division 79, Badge A3317.  Regarding online pharmacies and those selling thru them and also buying from them.   After his very stern and persuavive spiel that he would be willing to "help me" resolve this, I told him that I knew he was running a scam and trying to extort money he hung up.  Funny, the phone did not ring again!

Officer Matthew Barnes calling from the DEA regarding an ongoing Federal investigation. Definitely not a legitimate call.

Officer Matthew Barnes calling from the DEA.  Said he was calling regarding an ongoing investigation, between the DEA, The FBI & US Customs, regarding on-line pharmacies and their illegal activities.  He asked me if I knew anything at all about these types of companies.  I said "yes." And he asked me to tel him what I knew. I said that all I knew was that they were scam artists, just like he was . . . the phone went dead.  HA!
