You do not mention whether you have kids at home?
I am not suggesting for a moment that could be the solution, just an angle to look at
What times of the day are you allegedly ordering these films?
If you have no kids and you are 100% certain they are not genuine bills then you can only try putting your side to them.
Be prepared for them to say basically you have ordered them so pay for them, whether it could be an issue with the tv drive I do not claim to know, there are people with better knowledge
If it is a principle thing where they are saying tough luck you have ordered them, you could try retentions, tell them your issues, in most cases this will be solved by threatening to go to sky.
Good luck
