Who called from 4055787947

I keep getting calls from this number why ?

Hi there,
I have received a phone call from this phone number where I do not have any friends or relatives who live in USA. So I am just worried about the identity of the person who has phoned me.
Kind regards.

I am also in Australia and have had several calls from this number. Does anyone know who it is and why they are calling?

I also keep getting calls from them, I don't know anyone in the USA, did you find out who it was?
