Hello guys, can someone help me?

I paid for an dedicated server at worldstream and paid someone to config my server. But after 7 days after, I cant work with my new server, because I think that is a problem with my nameservers.

For example, by running an nslookup domain I get this:

C:\Users\Divvy>nslookup tugasapo.com
DNS request timed out.
timeout was 2 seconds.
Server: UnKnown
Address: 192.168.1.1

DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
*** Request to UnKnown timed-out
All my domains have the new server IPs:
NS1.ENIGMAHOST.ORG 217.23.11.221
NS2.ENIGMAHOST.ORG 217.23.11.222

The person who config the server said that config right the nameservers:

Web whois is showing old server IPs:
http://whois.domaintools.com/tugasapo.com
NS2.ENIGMAHOST.ORG 94.23.74.122
NS1.ENIGMAHOST.ORG 94.23.74.115

What could be?
Please help me fixing this issue...
