Hi there, can somebody please let me know if this makes sense: My last 3 gas bills: 22 Nov - 9 Dec 2019: $64.2310 Dec - 10 Feb 2020: $98.4211 Feb - 7 Apr 2020: 83.33$8 Apr - 9 Jun 2020: $466.27 I understand that winter might increase our gas usage, but to this degree? Going from around 2 300 MJ to almost 30 000 MJ - it just doesn't seem realistic?
