Sent my kids S4 in for warranty repairs, again, and they say this time it was user damage and want nearly $300 to repair it. It was sent in because of reception issues. I am baffled at how this can be user damage. Especially since the problem arose when it came back from repair the first time. Not only that, but now the camera doesn't work and they claim that is also user damage. It was working just fine when it was sent away. Tried calling customer support, but they haven't a clue and so I get transferred til the call gets dropped. I don't have hours to play these games. Who can I contact directly to get this dealt with?
