Помогите пожалуйста, срочно.
Если не трудно, нужен ещё перевод

I have already done that!
I've booked them yesterday
Have you picked up them?
No, I haven't been to the booking office (сюда в конец можно yet)
But I've (already) called them and they have confirmed that they booked the tickets in the morning
I've finished it but haven't sent it (yet)
I've called to remind you
