Who called from 6046391875

I keep getting calls and there is no answer. I wait a few seconds for someone to say something and still no answer. So I eventually scream into the phone to say "if you're not going to say anything, then stop calling.

got a call yesterday 8pm, didn't answer, and the voice msg started with a loud music, and then a femail saying this is "Alexandra from Call Select, Hello, Hello...", as if I called her.

someone spoke in Croatian and asked for the misses in my house,
She said this is Alexandra calling, and that she will call back later.
