Who called from 4356743778

Rec'vd a call from this number 3 x in 2 hrs.  Called it back - someone picked up and then hung up immediately. Called it a second time and it went directly to an answering service.

Called the # again and "kent" answered.  It sounded like a call-centre so I did the only thing any normal person would do and I hung up on Kent!

Recv'd 2 calls within 1 hour today.  I did not answer as no identification appeared on phone.  They did not leave msg.  
Not interested in anything they have to offer.
