I don't know why I chose the imperfective verb... Well, it's probably because in such cases I say something like: "Вы знаете, я вам там письмо отправляла. *Но почему-то до сих пор не получила ответа. Может оно не дошло?* It's sort of sounds more spoken.

On second thoughts, you're probably right, I'll change it a bit.
