Poor service DSTV box office staff couldn't assist me on this matter, please attend to it urgently

I have rented a Lion King Movie on the 4th of December on their box office, I've tried to rent it several times even called their help desk but I was not helped, I sent the msg on their whatsapp number still wasn't helped. In short I rented one movie on the 4th December but I'm charged more than R400 on that movie and I'm told that I rented 7 movies of which I rented one movie 7 times which was not successful until the 7th attempt. I'm a very loyal customer but I refuse to pay R1055 for my compact and a movie that was only successful once not 7 times.
