I had a broken screen and paid someone 3 to have the full piece replaced. The first attempt the part had a huge dead spot. The second attempt the screen cut out. The third screen has worked great but it's starting to de-laminate from the body. When they had put it in for a third time they told me I could not seek anymore warranty work.

The top and bottom corners are working their way up and along the left side I can see light creeping out.

Anyone know if what I can do to fix this? I was thinking of along it to another store and perhaps getting then to write a letter saying it was shotty work so I can dispute it on my credit card. Thoughts? Is there maybe an easy fix to this myself?
