Which sentence conveys the main idea in the passage? I am writing regarding a problem with my electric bill. Last month, my bill was abnormally high. My average bill has ranged between $400 and $700 during the past year. However, the bill for March was $1,750. Please send your service representative to check my meter and the circuits.
I would like to have this problem corrected in the next billing cycle. As you know, I have been a loyal customer for three years, and I have always paid my bill on time. I am sure that you will respond immediately, as you have in the past. I hope to continue as your customer in the future.
