I contracted for window tinting services. I rewuested a privacy tint, clear on the reverse and a mirror finish to the front. The company installed a mirror tint with a dark reverse and when I raised the isdue they assured me it would lighten to the required finish once dry. However yhat is not the case. The film remains dark and allows so little natural light into my living area that my plants have begun to die after just thrre days due to lack of light.
