When I applied for my original ASIC when they first came in, I sent off the certified copies of everything to CASA, no action for months, chased up through the system numerous times with a different answer each time - finally pinned them down to admitting my stuff had been lost somewhere between them and the security checkers, they didn't know where it was and I would have to resubmit the lot.
Having no option, I did that and 'successfully' got my ASIC, but there was not a squeak of apology out of CASA or any mention of where my original bundle of identifying documentation might be.
Probably in Nigeria now! What a great scheme it's been.
