I just received the same call! They gave me a call back number of 206-204-0739 and it was disconnected or not in service they also gave me a password and ID number or something to call back with.
They called on 25FEB16 I could not understand his Middle-Eastern accent. I only understood US Dept. and I asked to be taken off the call list.
On 01MAR16, I asked who was calling and they hung up.
