You're very sweet and nice and polite, which are very much appreciated. So I shall give you a word of advice: please don't use the word "awesome" in a business call. While it's good you think it is awesome that the unavailable agent can help you, the word itself says you are very young.
Love,
the secretary
And I know perfectly well that in five or ten years, it will be perfectly normal to use it - as my mother told me never to use the word "okay" twenty years ago, the very day I was told the exact opposite by the place where I was temping.
Awesome.
