So I filed a warranty replacement with ZAGG over a week ago. They sent me the new invisibleSHIELD , and I promptly returned both the front and back invisibleSHIELDs to ZAGG the next day. Well, a few days ago, I got an email from them. What the heck am I able to do? I sent back both pieces. I emailed Sidney back immediately asking her about the situation, and I never received a reply. I'm a first time customer for ZAGG. Is this how they treat all customers?
