Dstv ****med me,

So DSTV has rewards offers. I spinned the wheel and won a "movie on them". I then chose the movie to watch. However, there was no option to watch. I clicked on rent. I was given the code to send to them (5 numbers). I did. I was then charged. I contacted them but they said I rented it twice. Now, my question was, if the system rented it why was I not able to watch it?? They didnt respond. I feel ****med by dstv because as soon as the movie is paid, you are able to watch it and it stays for 48hrs. I was only able to watch the movie after getting the rental code.
