not sure if your missing the point or just trolling i ordered OLD s5's before the new S5+ was released and i would like to change my order...... i think it pretty reasonable since they haven't shipped my order and it would be very easy to do
I want to buy today, and tomorrow I want buy something else for the same money. Things just do not work that way,
At next time, buy for US dollars, and you have three days to pay.
I agree with Tupsu. Organizations have processes in place and some are too much of a hassle to reverse. It wouldn't be too easy to do.
An order was made and they processed it. I would only agree with you if you tried to change the contents of your order within 24 hours.
There is not really a huge difference between a bunch of S5s and S5+ so do not worry and just focus on what you need to do next.
