Who called from 2674394871

I have been getting automated calls from several numbers claiming to be Verizon Wireless, claiming to have an important message for a Verizon Wireless customer (they give the customer's name).  They are calling me on an ATT Wireless phone!  I have blocked the numbers each time I receive the call, and then the call just comes in from another number.  I called Verizon Wireless and they say it's not them.  I've been getting these calls for more than 2 weeks, sometimes several calls in a day.

Getting calls from this number every day for last two weeks. They hang up when the answering machine picks up.
