Good Day Banele,
You will need to make sure that the domain had not expired, unless if it was transferred to a different host,
Please also check if no one has registered the domain if it has expired.
Check on http://co.za/whois to see if your domain is still available under your details and when it will expire.
If it has expired and no has registered the domain, you would need to and let us know so that when we re-instate your domain services we should also queue the domain registration.
