Same thing happened to my husband today some papers to transfer if he doesn't call back to them. That they also have his social and address... The caller was a man with poor English. It sounded like from India or Pakistan. The number is also from Jacksonville, FL.
Someone just called me from this number as well and said there was a case filed against me and if I don't call them back, my case will be forwarded to the courthouse. It was a lady with an accent (maybe from India or Pakistan). I'm positive it's a spam!!
I also received a call today from a man with poor english and was told it was from the internal revenue service.It must be some prisoner,scam,or con artist.I just hang the phone.When I try to call back that number it alway sound busy.There are lots of crazy people out there trying to rip you off.If he calls again I'll try to record his voice,and then call the IRS and report it.
