Query: Don't throw away your receipt!

Product looks as if it would work well. HOWEVER, I ran into problems during installation and needed replacement parts. They were quite helpful initially with email but when I had to phone customer service they would not help unless I had the original sales receipt. So I now have a partially installed shield on the front of my iPod, with one corner sticking up,and a back without installation fluid with which to instal it. I can be treated badly for free; why should I pay for the priveledge? I'd probably give the product 5 stars if I could install it but feel generous with the 2 stars considering their customer service policy.
