Need ARIN routing registry help

[Meshier, Brent]

Level3 won't let us advertise our netblock because RADB shows it owned by 
Telkom South Africa, but it's clearly assigned to us by ARIN.  I've raised a 
question with ARIN, could really use someone there that could expedite.  On 
that note, when ARIN re-assigns networks, shouldn't they clear out related 
entries in the routing registry?
