I know how you feell because I share a similar exprenreice a few weeks ago when I was trying to get my yellow tinted iPad 2(64gb 3G wifi) screen replace at London regent street store. One of the genius bar staff was dealing with my case, and after I showed him my ipad screen in comparison with my other one of my friend's(which has very good contrasty and blueish screen) he clearly noticed there is a big difference between the two. Then he immediately call for a few other genius staffs next to him for second opinions and they pull out another iPad from their side (note this one has screen hue in between the two I was showing to them) then line them up infront of me tried to convince me that now you can see the differences is not so significant, claiming all the ipad have slightly different screen hue due to inconsistent manufacturer which is unavoidable, blah blah blah, Apple is nunmber one etc.
I did not buy into any of lame excuses from them trying to talk me out of it because I paid a premium price (£659) for a product expecting the same normal ipad I saw from the store demo not a second rated device. It just shows that what you see from apple store is not what you get, is this leaglle?
Anyway, i then insisted argued many times that my iPad needs a replacement and they just refused by denying the problem are theirs because as a pro tech guy they dont see anything wrong with it. Hence the situation got heated up and one more genius staff joined in trying to win my agument. And now making me looking an idiot by claiming they are proffessional tech people and because more than one of them see no problem with with it so why should I be complaining about it? I then said its easy for you to accept the device because you are not the one who paid for it!!
At that point I knew I wasn't going to get any replacement what so ever, because how can I win the argument from the whole genius team all standing against me. So, I kept insisting my request hoping to turn it around until I run out of steam and give up, but most surprisingly they ran out of patient before me and just walked away and shout out "Thats enough from you and you are not geting it replaced and I am putting notes into the system saying we have performed a diagnostic test with the screen of your ipad and it is perfect" then off she went without coming back to me, leaving me with the original genius staff standing with complete silence and tension between us. I have no idea why she joined in the conversation in half way and demonstrated such attitude towards me since she is not the one dealing with my case originally and yet she has the authority to conclude my case.
Anyway, I was wow by Apple's customer services and wow by Apple's product. They think yellow is normal, ike telling you the earth is square not round. Why should I be educated again? Have you ever seen the film call 'flight plan'? I felt like I was the one who have lost my daughter and called for help but somebody manipulated the whole flight crew to render me as an insane passenger.
Enough is enough, and enough from Apple. It's a free world. We have option to shop elsewhere.
P.S. My suggestion to all of you who gets the yellow gate idevice is that if you are not happy with it, you can just return it within 14 days of purchase. Don't bother replace it at genius bar, because you will most likely be facing those stubborn genius at apple claiming you are insane. Apple is number one and everything is perfect.
