Do you have to have a credit card to send in your xbox?

My Uncle is wondering if you have to have a credit card to send in your xbox. His xbox is expired. We called them and they said your 3 years been up already. So do you need a credit card to send it in?Do you have to have a credit card to send in your xbox?
No. You need only a valid e-mail address. One they have it however you won't get it back until it's paid up. Try to find out how much the repair / exchange will cost before it leaves your house. Once it's gone there's no going back
