Cannot get Telkom to sort out my issue.

On the 27 June I took out a new contract for my ADSL and data with Telkom, I requested that the email address I had was the one that was kept, Helen at Clearwater said that there was an issue with the email address and she needed to put one onto the system, I explained to her how important it was that my email address does not change, she said I should not worry. From Monday last week I have called Telkom every night because not only could we not receive email but we could not send due to the email address being deleted. I called billings Kedibone told me it had been sorted. It is now the 6th July and I am having to use Webmail because even though they have given me back the email I need, I now have two which I didn't want. I can receive mail but there is no link to the outgoing server, this has meant a week of possible lost quotes and lost invoicing. <br> <br> No words can explain the frustration or fury in this issue having come about due to no one being able to solve the problem and everyone telling me it is the internet department that can fix my issue, however no one knows where the internet department is or how to contact them.
