Yours sincerely,

no, just kidding. things to include:
1. detailed description of what went wrong, make sure to show your disappointment.
2. explain why you think the company is at fault
3. what you think the company should do (follow up actions)
4. ask the company to respond to your letter and include your contact

I dunno man. I mean I basically have to stretch out the sentence "I regret to inform you that there has been a mistake in my electricity bill." into 500 words. That's like miracle-work or something.
