Have you received both confirmation emails? It seems to be a two step process:
1. "paxum.com: Withdraw Funds By Wire Request Initiated"
2. "paxum.com: Withdraw Funds By Wire Request Completed"
In my case (which was 6+ months ago) the time between the two emails was 6 calendar days, then there's the usual wire delays on top of that.
BTW I notice my wire was exactly $AUD25.00 short of the amount that Paxum stated they were sending.
So I got charged $USD50 by paxum
Plus $AUD25 by some intermediate (possibly the third party that Paxum uses)
Plus $AUD12 by my bank
So all up I paid about $USD80 in fees just to get my funds.
