I'm in the same boat, this number has been calling all week, going to VM and not leaving a message... I finally answered it yesterday out of frustration, got some Indian guy asking if he's speaking to Jackie Fisher, I said "yes and don't ever call me again!", he then mumbled something and hung up... I didn't receive a call from them today, not sure if that's a good thing or bad thing. Maybe my name and number are now plastered all over fake documents in ME, USA.
Got 6 calls today during work, another came in just after work. A very man with a very thick accident asked for me, when I told him yea he had reached me and this was the 7th phone call today, he replied, "7th". I advised yes and what could I do for him as this number had left absolutely no messages after each call. He stated at that time, only 7? I'll call you a hundred more times!" I told him to go where the sun doesn't shine. Then hung up.
This number had been calling me for 2 days. Never leaves a message so on the 5th attempt today, I answered. A man with a horrible accent and inability to speak English clearly attempted to ask for me. All I could understand was (or think I understood anyway) was "United States...... Department". He even tried to spell when I told him I had no idea what he was trying to say and I still couldn't figure out.
