Scammer.  Says name is Kimberly with Grant and Associates and they have a "Pending Case" that they need to hear back from my attorney today or they will "submit my case" and state to "govern myself accordingly".
LOL SURE
I have been getting these calls for about a year...why haven't they "submitted my case" yet?  Nothing on my credit report....will keep deleting the messages.  They never even say my name.

Harassing abusive [***] for brains Kimberly with grant and associates called me today. Left me a threatening phone call, so I'm reporting it to as many legal authorities as I can locate as well as filing a complaint with BB.

I have been getting these calls off and on for 3 years, they call every few days for a while then stop for a while, if they pick us up at the same time we can share cells :)

Scam debt collector.  Best to report or at least ignore, but if you do talk to them, do not give any personal information or agree to any settlement.
