I had the same thing. They have called several times, can't understand them, I did catch something about government something or other. I don't even answer. Why can't the police or FBI do something to these scumbags.
They said they were with US Government Loans and asked for Randal. They send me texts as well and I'm not Randal and continue to ask them to stop. When I got them on the phone I asked to speak with someone who could help me stop these calls and texts and she just said thank you and hung up.
This number has shown up on my phone's memory a time or two in the past... I NEVER answer calls from numbers that I don't know. But this time there was a voicemail. Out of curiosity, I listened to it. It was creepy. It was as if my number was dialed unknowingly and all's I heard was about twenty seconds of a female voice next to the phone and many background voices, all in a language I couldn't recognize.
My phone rang twice and before I could answer they hung up! I tried to call number and it said call could not be completed!
THIS PHONE NUMBER WAS 1-202-111-000
