Rented a movie at Box office

Good day I have rented a movie on box office online on 10 May 2015. After i paid for the movie and started to watch the movie the wrong movie was playing. I phoned box office and they said they will look at it and phone me back in half an hour (spoke to daniel ref nr ***). After an hour he still did not phone me back and I phoned again but then was told there services is off and they can not help me but will phone me the monday after 3pm.<br> No one phoned and I phoned again at 5pm to ask for help and was informed that they could not help me it is not there problem i should email them. Well i emailed them got casenumber (***) and after numerous emails explaining my problem asking for help or my refund because i did not watch the movie i was informed today 18 May 2015 that i should enter the chat live room and i got adverti*****t for debit order at multichoice! I am so frustrated because no one is willing to help or sort out my problem or will refund me every time it is a different storie! This is so pathetic and i just wanted to watch the correct movie or get my refund! Is this to much to ask for! This is the third occurance the first two is still unresolved!
