OT: set up Reverse DNS zone

[ram]

The APNIC site is extremely unhelpful in setting up new reverse DNS
zones

I want the the NS record for our servers to be pointed to our DNS
servers and nothing has done inspite of giving the request on the APNIC
page 
http://www.apnic.net/services/dns_guide.html

http://www.apnic.net/db/domain.html

They have not setup the the NS record for my zones 
242.162.202.in-addr.arpa . We recieved a mail from them and took the
necessary actions but nothing has been done since 1 week now 

Can someone guide me whom can I approach for proper help 


Thanks
Ram
