so i bought an invisible shield off ebay and registered it. when applying it i was inpatient and the top two corners didn't stick down. now, 1 1/2 months later, where the corners didn't stick, its all full of lint and stuff from being in my pocket. i know that ZAGG doesn't replace them if you applied it wrong, but what is a good excuse or something i can say/do to replaece my invisile shield? ps i only applied the back, the front was never applied.
