Multichoice really bad service

I rented a movie from Boxoffice online, after paying the rental amount the movie was still not available, I then phoned Multichoice and they advised me to rent the movie again, which I then did, the movie was still not available after i paid twice. I then used a different card to see if that maybe works which it didn't. I phoned in the next morning and the lady did not understand i rented a movie online from Boxoffice and not on the decoder, after a long struggle she then talked to someone else at the contact center to sort it out and they will phone me back within an hour, which i never received further feedback. They then sent me a message to rate my service which i rated 0 for everything, and this morning i received a call asking why and that they will investigate my issue and come back to me, which they also didn't do. Really bad service.
