Who called from 4127738561

I am sick and tired of these bozos calling.  Now their number is blocked

Some variation of this number calls all the time.  No message, ever.

I have been receiving calls from them over the last month on my cell.  They asked for a name close to my name and then they hang up.  Why?  The last time it was a man and previous times it has been a female.  While about scams.  Where are they getting our numbers to call from?  Thanks.

It's a company called Share Group.   http://www.sharegroup.com/ 

Their core business is comprised of outbound telemarketing services: fundraising, membership mobilization and affinity sales calls. We are however a full-service provider, with offerings that include inbound calling programs, activist recruitment, online giving options, e-mail address collection and e-mail pledge fulfillment.

They have called each of he last three days, just said my name to the voicemail, and then hung up when there was no response..
