3 years to Change an account & cancel a line

It has been 3 years of asking Telkom to change the Telkom telephone account into our company name and cancel one number. To date this still has not happened. Today, after numerous calls some tells me there is a form I need to complete to cancel a line - not even there retentions email reply states there is such a form. I am highly frustrated and angry because you can never get hold of the retentions department who actually handles this. <br> There staff are very unfriendly and unhelpful. All they do is push you from pillar to post and never get anywhere and no one to speak to who can actually assist you. There call centre agents if they don't like that you are angry after 3 years just cut the call on you. I think it is time to report them to ICASA.
