Can't change a phone number

I have been trying for 2 weeks to get the number of my business changed in the online white pages.<br> <br> I have been sent from telkom, to Trudon who manages the whitepages.<br> <br> Trudon tells me only their consultant Jennifer Walter can change it.<br> <br> Jennifer does not respond to emails or seem capable of changing the number.<br> <br> This is a very simple admin task which should take 5 seconds but seems impossible to do! No wonder no one lists on the yellow pages or telkom directory anymore.
