reverse dns not propagating

I have an ns server with a reverse zone that isnt propagating its way out to the internet.
There are other records held on same server that are working properly, it just seems to be the reverse zone for my reverse lookup of my mail server.
The configuration is redhat9 using bind with a webmin interphase

when i do an nslookup of our dns server it works fine but no other outside dns query works.
example of nslookup of ns1.cyberbranch.com
 > 63.146.84.165
Server:  ns1.cyberbranch.com
Address:  63.146.84.159
165.84.146.63.in-addr.arpa      name = mail.csc1.com
84.146.63.in-addr.arpa  nameserver = ns2.cyberbranch.com
84.146.63.in-addr.arpa  nameserver = ns1.cyberbranch.com
ns1.cyberbranch.com     internet address = 63.146.84.159
ns2.cyberbranch.com     internet address = 63.144.121.10

here is the actual record stored on our dns
$ttl 38400
84.146.63.in-addr.arpa.      IN      SOA      ns1.cyberbranch.com. hostmaster.cyberbranch.com. (
                  1080152107
                  10800
                  3600
                  604800
                  38400 )
84.146.63.in-addr.arpa.      IN      NS      ns1.cyberbranch.com.
84.146.63.in-addr.arpa. IN      NS      ns2.cyberbranch.com.
165.84.146.63.in-addr.arpa.     IN      PTR     mail.csc1.com.

I have asked our vendor (qwest) wether there was a problem with reverse dns and is it allowed. They sent me back saying that they do not have any restrictions on reverse dns. I have an email with their dns department but it takes so long for them to reply I want to gather more detail.

This is totally normal. As you can see below, your server is not the master for this zone.

You have to ask qwest to delegate this zone to you. They will then instruct their DNS servers that yours is the master server for this zone.

dig in ptr 84.146.63.in-addr.arpa.
