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

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 .
