'Intekom' isn't a valid domain name, but intekom.com and intekom.co.za are both domains that were use by Intekom, and are currently part of Telkom Internet, but the Intekom brand was phased out though some remnants remain. For example, compare what you get at webmail.intekom.com to webmail.telkomsa.net .
I am able to do DNS updates on intekom.com or intekom.co.za, but I think the last of the Intekom employees that were at the call centre were outsourced a year ago and forced out of the outsourcing company by the end of last year ....
