Letter closing

[ramul45]

While closing a letter to my superior asking for review of an order, I wrote as the last para
"Thanking you,
Yours sincerely,
.... "

Perhaps there could be alternatives, but is this constructionally wrong? There has been an argument.
Thanks.

While I'm sure that "yours sincerely" is OK, I don't know if "Thanking you" it's truly constructionally correct. I'm but learning how to write formal letters too, and I've never seen this construction in any book or forum.
If I were uncertain I'd have used another alternative.

Both "Yours sincerely" or "Sincerely yours" are perfectly acceptable complimentary closings. It's the "Thanking you" part that doesn't quite conform with standard letter writing format. Perhaps instead of "Thanking you," you could construct a final sentence such as "I thank you for your attention to this matter." or "Thanking you in advance, I remain " (and then you'd skip down two vertical lines and add "Sincerely yours".
