Yesterday.
I did call last week and nothing happened, and when I called yesterday they had no record of me calling earlier.
This time I called them back 4 hours after hanging up (they can't do it over the phone, it has to be sent to the team in Australia) but they could tell me exactly what the previous agent had done and to wait 3-5 days - but as it turned out, it was overnight.
My guess is they didn't know how to handle these last week, but they must be getting a lot of calls and have got the process down pat.
