I bought an iPhone a week ago. I love it and I love apple but it's not working as it I expected it: I get a lot of dropped calls, safari crashes, a lot of lagging among another issues. I went to the store I where I bought it to return it. Here in Portugal you can by law return any electronic equipment you buy within 30 days of purchase. So I went to the store to return it and they didn't let me. The iPhone and accessories are all impecable with no scratches but they said there's an apple policy that says people can't return iPhones, they can only send them for repairs. Is this legal? What can I do?
