Dont use the Direct Illumination option, instead just get faster and cleaner renders with using it as a "GI" light
Also tick "Compensate Camera Exposure"

i checked this.. its even create more noise
you can download the scene

It's because the glass/plastic on the front face does NOT have "Affect shadows" enabled. Enable that on refraction and it will be much better
