煤氣賬單Gas Bill

我今日收到好煤氣單，嘩!!! 我居然要交５００元煤氣費!!!! 我心想：我一個人住也用了這麼煤氣，簡直難以置信!!! 然後我再仔細地看，才發現原來我因為沒有按時報錶，所以煤氣公司多計了我的用量．．．從４月的讀數３９８４到它估計６月的４０２５，足足是４１度煤氣，但實際呢？請 看上圖，其實只是３９８８而已．．．正確來說，我兩個月內只用了４度，只是它估計的十分一．但最無奈的還是我沒有辦法拒絕繳費，煤氣公司只會於下期賬單扣 除多繳的金額．我粗略地估計我大約可以少交近２年的煤氣費．GOD!!!!

I have just got a bill from Towngas. Oh!!!! It's totally $500 for these two months.... but I was wondering why. I'm living on my own from March. I shouldn't consume that much.

When I read the bill closely, I found it was over-estimated how much that I have consumed.
It's 10 times over what I really consumed for last two months. I MUST pay the amount shown in the bill this time. Towngas will not refund the amount that I have over-paid. That amount will be used to pay for the next bill. However, I over-paid too much this time. I think I won't need to pay the bill for next 2 years.
