Poor service all round

I upgraded my adsl account to 4Mbps after seeing an ad that gave me a media box for free. First I struggled to get my service going after spending 3 hours on 4 calls mostly hanging on for a service consultant, then I finally get my media box delivered after 7 weeks and now I must pay extra to get the media box activated. I complained but got no joy from the technical or accounts department. When I requested to speak to a manager, he/she was conveniently in a meeting and would call me back. I am still waiting. As all calls are recorded I want Telkom to listen to what was promised and honor their agreement, otherwise it leaves me no option to find an alternative service.
