Don't release any info out.  I called this number and they ask for you DOB, address so that they could send informaiton on why they've been trying to contact you!  What in the world?!  You shouldn't need to give out any info to an unknown company.  This is definitely a scam.

It's a scam.

Don't release info to them.

No message left.  When I dialed the number back, a recording said "This number has no applications assigned to it".
