Recently we changed our gas supplier from Bord gas to Airtricity. In the past two months we don't recollect using heating even once as it was very warm and there was no need for it. Still, we received a bill for 296E for two months. In the past we have received bills from 50 euros to the max being 105E at the peak of winter. When we talked to Bord Gas, they said the previous bills were estimated bills but this is the correct reading bill so it has to be correct. But how can one get such a huge bill in summer that too when you don't even put on the Gas switch. And its just impossible to pay about 300 euros when we were expecting it to be the minimum possible as we didn't use heating. Bord Gas representatives were uncooperative and said we have to pay the bill and they can't do anything as we have switched to another operator. How can we deal with this issue
