2015 Honda Accord coupe, bought this car used. The back window had film on it, bubbling but wasn’t tinted - odd to me. Not even sure why this previous owner had it on there, no tint.

I pulled it off like an idiot. Well, now half of the back window you can’t see out of it. A portion or layer of the film stayed and now it’s ’frosted’. What should I do? How costly?

Thanks in advance.
