Our business just got a call from this number

I just got call from this number asking for my full name, register name, address and kine of business.

They called me on my cell phone (Sept 16th at 15:33 pm) which had my old business number ported over to it when I retired.  When I inquired "How can I help you? (I was 24/7 on radio system maintenace) they stammerd and then hung up.  Previously, on Sept 14th about the same time, I had ignored the call as it was annouced as "Unknown."

They have now been assigned the name "DialerA" and a ringer tone "Silence".  Have a "nice day" you auto dialer freaks!

Got 3 calls from this number on different days 9/16/10 3:11pm CST being the last one. NO ONE WAS THERE. When you are running a business this is annoying in every way possible.
