Personally, I don't think your problem rises to being actually scammed, but you did end up paying for something you didn't want. As long as you did not watch anything on Now TV then you maybe entitled to a refund.
I suggest that you contact Resolver at the following URL:

They may help you get your money back if they believe you have a case.
