That really stinks. How long ago did you purchase? Can you call up Apple Care to see if you can get a solution since the local store is not being cooperative?
I purchased on the 21st of july and the macbook pro arrived on the 26th. I called the applestore on the 4th of august and set up my appointment for the 5th since they were busy on the 4th. So, it's a pretty recent purchase.. So if I call applecare maybe they can sort it out?
Thanks
