About hello123

Hello everyone, I was wondering if you could please clarify something for me. I live in a 2BR unit with 1 other person, and we don't have gas cooking... my quarterly bill came to $330.19 and the one before was 160.60 (when we were both away for a month)... We always thought it was due to high gas costs in NSW but speaking to others, it seems that we are being overcharged... when we first moved into our unit a couple years ago, nobody came to read the meter, and nobody has come to read the meter ...
