I have been getting a call from 520-000-000000 too. I have not answered it and they do not leave a voice message. They have called me twice this week. I am getting really annoyed by it. I wish I knew why this is happening.
I've been job searching, nothing in Mexico City obviously and a 52 664-3860405 called me and I answered because well, you never know right? Especially while job hunting. The jerk asked if I spoke any Spanish and I actually can understand it very well and speak it well. I told him know and he started speaking grossly sexually to me and cussed me out towards the end. I didn't let myself. Ugh horrible way to start my morning.
I received a call from this number yesterday afternoon and believe firmly that it is the courtesy phone at St. Joseph's Hospital in Tucson AZ and/or Tucson Fire Department line because of a former boyfriend's urgent calling during his substance abuse meltdown/dialog (minute-2-minute mad texting to me) whilst being in St. Joe's and being discharged to a different facility. He was urgently trying to get me to come pick him up, when all the while, his insurance will pay for medical transportation and certainly EMS service in his condition (which is I am sure how he got there in the 1st place). I did not answer the phone, I never do unless I recognize the number.
