By default, saves are transactional, i.e. when you try to save your 3 entities (pessoa, email, telefone), DevForce processes them together as a single unit of work. Either all 3 saves succeed, or they are all rolled back.
If I understand, you want to save all 3 entities created (pessoa, email, telefone) in 3 different transactions. If any of them fails, only that particular save is rolled back. If this is the case, you should call Save (or SaveAsync) for each entity (or group of entities you want in a transaction).
Please let me know if that's what you are looking for.
