Closing for a letter when I don't want to say "Sincerely" or "Regards"

[Zoidberg]

Letter to a mortgage company which is in the process of continuing to screw me (re/my old LA house damaged by Katrina). I certainly don't want to say anything like "regards" or anything, and can't say "piss off". Nor can I say Boomshanka. (bonus points if you know the reference without googling it)

Suggestions?

[ztirffritz]

buggeroff? Maybe their not up to snuff on the British idioms.

[clay]

Don't include a closing. Just put your name after the last paragraph.

[Zoidberg]

Yeah, what clay said is what I'll likely do.

[dochocson]

"Cromulently yours,"

[$tevie]

The closing is meant to be polite. Why be polite?

[michaelb]

I would use sincerely. Both to be polite as suggested by $tevie, and because if this ever ends up in Court it will look better that way.

[Gutenberg]

"Aggrievedly yours" ought to do it. Or "Disgruntledly."

Or with the last sentence you could say "I am expecting a prompt and dissimilar reply to the one I just received.

"Zoidberg."

Edit: Geez, my spelling.

[Zoidberg]

The odyssey my wife and I have trekked through thanks to this company really gives me the right to spit fire at them. But I'll stay civil.

Yours truly,
