My neighbour heard it, because my meter is on the outside wall of my house and she was moving my bin back.
This part is slightly amusing.
My neighbour is also the granny the granddaughter I was looking after. (My son married the girl next door.)
She rang the bell and I thought she had had come to visit our poorly granddaughter.
I invited her in and she said no, you need to come now! To complicate matters, DH had hidden the key to the gas box and she had to run and get hers, so that I could investigate.
I then left her with our DGD, while I did battle.
To complicate matters, we are in dispute with Scottish Gas over a faulty smart meter, which indicated we had used more gas in three months, than in the last ten years.
The Ombusman is now involved, because they have been taking £700 out of our bank account over the last two months.
Scottish Gas have now realised we are not a pushover due to teh fact that DH has compiled reams of comparison spreadsheets of our usage over umpteen years and they finallyhave admitted the meter is faulty, but they keep palming us off. Today was the last straw.
What if one was not as savvy as us?
