I got a call from this number yesterday at 6:35 PM on my cell phone.  When I didn't recognize the number, I didn't answer.  When I played the voicemail he left me, I was cut off (as if the recording started when voicemail kicked in and I only got the ending bit) which said "...allowance program, and again my name is Jeffrey Klein and my number ...., and it is IMPERATIVE that you call me back".  I know for a fact that I have no debts, so I don't know what this would be in regards to.  However, ever since I got this cell phone (from Sprint), I've gotten many odd calls from all over the country!  I registered on the DNC list, but I wonder if that only applies to landlines, not cell phones?!  If anyone has more information about this that they'd like to share, please email me at [email protected].  Thanks!
