So here it is, I went in to EE in October and showed them the issue with my wifi, they wanted to send my phone off for testing but as I hadn't backed anything up I said I would go back in, I had my baby a few days later so I didn't have the time. My toddler smashed my screen just before Xmas and now EE are saying they won't send it away now because I've had my screen fixed elsewhere even though they remember me going in before the screen was smashed. Does anyone have a link for Kitkat as EE plugged my phone into their machine and.are saying I need to downgrade the software to sort the wifi issue.
