Called my cell. When I answered, he used my first name and said it was "Dave Johnson." Line was bad, I asked, "Who?" He responded again, "Dave Johnson." I replied, "yes?" because I actually know someone with that name. Then he hung up immediately. This was on 8/30/11.

After being hung up by this number 9 times in the past 2 days, I looked it up here and found this.  Then 15 minutes later, call 10 came in and I snapped.  I called back (no access to human intelligence unless you have an extension number) so I left a message in la-la land giving them my phone number with instructions to not call my house again or charges would be filed for harrassment.  Not that I have a clue who to file against, but here's hoping!

kept calling and hanging up

Some company called "Koncept Interna" has called about 10 times today ... line just goes "blank!"

I have received half a dozen calls from this number over the past 10 days. I am extremely annoyed that each time we pick up, they hang up. What's the point??

No answer.
