Film too large

Unfortunately, the protective film is too big is the right and left on the Lumia 930.
The Service agrees've immediately got new film, but attached here again the same problem, the film dust-free right and left it is slightly above (bearable) but once you put as the Lumia 930 in a silicone shell.
To warp the film and is almost on alone, because it is easy to cut large.
You can tell that was just not tested the film in conjunction with the Lumia 930
sorry so the film is not to be used.
And a star too much.
