Hey I just installed cPanel on this server and my vanity nameservers are not working.

This is what my DO domain zone looks like:-

$ORIGIN delhideveloper.com.
$TTL 1800
delhideveloper.com. IN SOA ns1.digitalocean.com. hostmaster.delhideveloper.com. 1478584264 10800 3600 604800 1800
delhideveloper.com. 1800 IN NS ns1.delhideveloper.com.
delhideveloper.com. 1800 IN NS ns2.delhideveloper.com.
delhideveloper.com. 1800 IN A 139.59.11.192

In cpanel I have:-

1. Created 2 NS records for ns1.delhideveloper.com & ns12delhideveloper.com.
2. Created 2 A records for the same with servers IP address.

In my godaddy domain management I have:-

1. Created 2 glue records for both nameservers with the servers ip address.
2. Added the nameserver ns1.delhideveloper.com & ns2.delhideveloper.com as the name servers of the domain delhideveloper.com.

Its been 2 days DNS propagation is not complete. I am very sure that I am doin something very wrong. But what is it???

This is the exact tutorial that I tried to follow:-
https://www.digitalocean.com/community/tutorials/how-to-create-vanity-or-branded-nameservers-with-digitalocean-cloud-servers
But was not successful. I wanted to actually create Branded Nameservers (Not Vanity) as I want to be a local hosting reseller. I am unable to decide which DNS zone to change in which step (The Droplets DNS Zone or the cPanel DNS Zone). I want most of the DNS records to e handled by cPanel no the DO Zone Editor.

Can you tell me exactly where am I going wrong.
