Who are these people. Rude and give no info.

This number has called me twice. The first time they said I owed money from a hospital visit, but when I asked about dates they hung up. Second time they called they asked "is *my full name* there? " and when I asked who was calling they hung up. Mind you, this was after 6:30 pm.... the first call was at nearly 8 pm. so what doctors office is going to call me so late? So sketchy and annoying.

Same here...then they left a message with a case number..I called back..they said I owed on a chevron card from 2003 and were suing me and added lots of interest. I said well it doesn't sound correct.  When was the last purchase. When was the last payment. He started flipping out .yelling..he didn't have to give me any info and he'd see me in court..I laughed my [***] off.
Ifffff you answer just hound them wI think questions..make questions up. They will hang up.  It's a scam.

Called at 8pm and left a voicemail, after 8 seconds of silence a woman's voice said, "Really? 35 more minutes longer? 35 minutes of my life..." in a really irritated tone.  No idea.  Very confused.

Calls but never leaves message
