I called back. It answers because the timer on your phone runs as if someone has picked up the call. But you can still hear the phone ringing.
Number called me back again, and theres is NO ONE on the line, only a female voice pretending they can't hear you: "Hello? hellooo? hello?"
And then the line gets cut. BLOCKED.

Rang back 3 min later and no answer

I called back the number 0491 154 323 but the phone just kept ringing
