I just got a call from this odd 8 digit number.

I normally don't answer calls from unknown numbers but I have some people doing home improvement work for me and I've had to answer all calls for the past two weeks.

When I answered, they didn't say anything, stayed on the line for a few seconds, then hung up.  

I assume it was to make sure that my number was valid so they could sell it to scammers/telemarketers.

And yep.... an hour and a half later, I'm getting scam calls from whoever they gave my number to.  Figures.

They just called me again.  Since I saved them in my phone as "scam" it was easy to ignore.  I thought I assigned them "no ringer" tho, must have goofed up.  Need to go back and redo my settings.

Have called around 12 times in the last 2 days. Wont talk when I answer and then hangs up. Whatever it is its dishonest and no doubt they suck big &^%$

I'm getting calls from this number on my cell phone. How can that happen that the number is 8 digits?
