honestly I hate it when we're all excited over a new product and then it all goes wrong
it's gut wrenching. The only thing that can somewhat fix it is excellent customer service which you haven't had.
Closest I had was with an iphone, ordered it, waited for it, arrived completely dead. Called applecare who just didn't believe me, "have you charged it" blah blah. Luckily there was an apple store close. Went in, showed them the phone and the guy must've seen my totally sad face and said OMG cheer up we'll fix it for you! They managed to get me a new phone from another store, set it up, installed a screen protector free for me, gave me a choice of a free case... little things I know but I felt like they put their arms around me and made it better.
If samsung want to REALLY compete with Apple, they need to get their support up to standard because a bad taste not only puts off that person but they tell 10 other people who avoid samsung too.
