I received a call from this number from Lou
With international courier services.
He gave me a docket number and said I need to call by Wednesday (in 2 days) or they are coming to my address. If I'm not home. My place of employment .  
By reading posts with similar situations. It seems related to payday loans.
I haven't called back but contemplating.
I had a similar call 5 months ago.
They called my family. Called my place of employment and told them they are coming to serve me papers at work .
I was embarrassed! The lady at the front desk said in front of my co workers that someone is asking for me and has a claim against me to call them back.
I don't want to be harassed at work anymore.
It's stressing me out .

Did anything ever happen with this....I got the same call yesterday on my cell, today the called my home

yeah, they made me sign for a notice, it was a validation of debt.

Nice try there, you scrawny goat rider. People don't "sign" for a validation of debt. They receive one, within 5 business days, of initial contact with a legitimate collector. By MAIL. Not e-mail or fax.
That's the law fraud-boy. Don't try to play here. There's always someone here that will take pleasure in skinning you alive. You little frauds are nothing more than an appetizer to us. You're nothing.
Skeff Ett Liv!
