Can I sue radio shack?

I bought a xbox 360 wireless headset from radioshack online and the first day it got home it didnt even work so i call then and they said I had to pay for shipping and i didnt want that because why do i have to waste my money on shipping once it wasnt my fault right? so i went to the store and they said theyll deal with it and I check back on the bill 3 months later and its still on there i call them and they know nothing about it i gave then the item and they didnt give me the money back or returned it back to me can we sue them? or make them pay more then i payed for?
