Multiple calls regarding my electricity account. When I challenged the caller re: supply address as the phone account was under a business name, when they refused to tell me I advised and ended the phone call.
Another call - i answered however when I advised them they had already called me today she hung up. Missed call again. Caller number now blocked.

Received multiple calls

possible spam, they didnt speak and hung up after 10 secs

Took several seconds of silence before someone spoke so I hung up.
