Caller said Hello then hung up, I called number back and was told to get off the line and they hung up again. I called back again and the person was really rude and said this is an emergency line, stop calling the line, I told her no you called me first and hung up so I’m trying to work out who this is and she said I did not call you and hung up again.
I sent them a message with a screenshot showing the incoming call from their number then blocked it.
