Box Office fails to deliver

Yesterday afternoon I paid for a movie to watch online last night. The payment was successful and I logged off. When I logged in again last night there was a double bill (2 x R30) on my statement and the same movie reflects on my account twice (although it says that I have only hired one movie). On top of that it will only let me watch the trailer. If I try to watch the movie it asks for payment again.<br> <br> The movie is still valid and I still can not access it. My understanding was that the first movie was free?<br> <br> At the moment there is only one deduction (R30) on my credit card. It is obvious that the online system (at least) does not work properly. I would like a refund please.
