Billed for a movie we never saw

On Sunday 8 February we tried to rent the movie The Maze Runner. We received an sms stating the rental was successful and the movie would be availble to watch in 5 minutes. Till now. 5 days later - no movie to watch. Funny thing is the movie was billed to my box office account. On Tuesday, via Facebook Messanger, I was told the charge would be reversed from my account and they would assist me later in the day to rent the movie when I was at home. I only needed to send a rental code.<br> <br> I sent the rental code only to get a reply hours later to state the code is only valid for 15 minutes and I must call in to get assistance to rent movies. I don't need the assistance to rent movies, I want the charge on my account to be reversed because on 8 February I NEVER received the movie we attempted to rent and I don't see why I should be billed for a product I never received.
