Who called from 9724747287

Called and didn't identify themselves and wouldn't say who they were and when asked they hung up

Just an SOB criminal

I've been getting alot of these calls lately, and so i've been fed up with it all. They called, i said hello. they asked if i was Malala?? i didn't answer and i asked who was calling and they hung up. Ughhh

Called me three times with a couple of minutes between  each calll. Didn't leave message

call & leave no message. Running down my battery!
