I've been through this one previously. They don't want to leave me alone. In an effort to get them to go away this time, I simply said "I've spoken to you before, and have even sent you the money you requested. That entire problem should have gone away." Then I hung up.

They did not call right back.

The first time this happened it gave me a good scare until I understood what was going on due to reports here. I could have gone round and round with them, but did not want to get worked up this morning as I need to concentrate on working rather than a scam. I'll call the DEA and leave this number though, and block the number.

Thanks to everyone who leaves notes about this scam. You have saved me lots of mental sweat.
