Zagg Invisible Shield leaves PERMANENT damage on my Touch

I was pretty excited to get my Zagg shield, as I had heard nothing but good things about it. I got it and the process looked extremely tedious but I decided to do it anyway. So I did, but decided to take it off. (about 10 min after applying) while it was wet. I took it off slowly but noticed it left a couple marks, and one giant one on my screen. I've tried everything (goo-gone, purple mist, etc) to get it off in vain. I'm pretty sure its not a spot now, and it may have pulled the touch screen membrane off. I can still use the parts where its damaged but it looked terrible and doesn't feel right at all. I need some help or relation. Thanks.
