We actually received 2 different calls from two different 876 numbers in about 3 hours.  They stated that my daughter had won some prize out in Las Vegas and gave us a 702 area code number (vegas) to call and claim the prize.  We alerted the phone company I have and the local authority on these calls because they are a true scam and they are now starting to call my neighborhood!!!  Do not call any of these numbers back.
