When & How did you get your "Original Documents" Back??

Hi All, Wondering if anyone could share when they got their original documents back..? I've had my passport delivered (first adult - application to delivery took 28 days in total), but i have heard nothing about all the official documents i've sent them to support my application (which include my other nationality's passport!). I have paid the extra money so as to get these documents back securely, but no idea what's happening (and my application page on the PO says nothing about this topic either).. Any info will be of great assistance! Thank you,
