Who called from 3073168781

I do not know anyone in Cheyenne, WY, nor do I know anyone with the 307-316-8781 phone number.  The call only rang for a small number of rings, and they left no message.  I'm not interested in what they have to say.

This is a number is the 5th number that has called me asking for Betty Walker. And I tell them wrong number or even yell at them and they hang up. Getting really annoying!

Called my cellular phone.  Picked up, no sound.  My cellular is on Do Not Call registry.

Have no idea who this is and as they never leave a message it's obviously not important! Just wish they would stop bothering me!
