Who called from 3052099901

I'm also with T-mobile.  Call from this number around 9am, didn't answer.  No voicemail left.

Left me a voice mail at 9:42 am on March 29 regarding a reward card for visiting an undisclosed Web site previously. It asked me to press "1" to get the reward card or "2" to be taken of the call list.  I did not a call it back; however, I checked my number's registration at donotcall.gov, and since I only registered this number on March 15, 2013, not enough time has passed for me to file a complaint.

Rang then hung up.  Missed call..

Sprint Nextel is my carrier.  If they sold my mobile number to this company, they are worse scum than the spammers themselves.

This number just called my cell phone also.  I didn't answer it because I didn't recognize the number.
