Who called from 5152593543

Have got 4 calls from this number today. Nobody on line except once then they asked who I was?

I answered and there wasn't anyone there after saying hello a couple of times someone finally responded

I've been called four times in the past three days.  I've blocked the number.

Called, I answered, said Hello many time and then just disconnected.  Obviously scammers

I have also blocked it.  And yes it was an Indian.
