Who called from 8562465237

Sounded like a middle eastern who said they were with the Federal Reserve.  We hung up immediately.

Threat of US legal action if I do not return call.

Same as above. threat of US legal action if I don't return the call.

Just received the call - recording said he was james Caston?

Got a call from (856)246-5237 threatening legal action, returned the call but the Indie who answered would give no info until I verified my identity which I did not, so he hung up on me.  Googled the number out of Camden NJ to Teleport Communications Group.
