Book My Show — Stream Rental Movies won't play in TV and there is no cancellation also for this.

I Rented movie Spider Man No way home via my Smart TV, it was successful till the Payment made from the TV itself. But once I start to Press Play and wait for watching the movie isn’t playing at all in TV . It throws up an error “saying something went wrong”. If this moview isn’t playing at all then why this has payment option in TV. This such a clever cheating CUSTOMERs. On top of it there is no refund or cancellation option also, very cheap tricks in looting CUSTOMERs money. I wish they had some other competitors at least then would they have developed..
They know no one can book a CONSUMER COMPLAINT against them.
I tried to send mail to CUSTOMER support also, but none of them reply back with solution even after 2 days. If they reply post 2 days they give the same ### FAQ they give which is useless
