Mode Phone Gift Codes

I was sent a code for a free Mode Phone, how do I use it? I have already redeemed the reward on Current, how do I use my code? I thought this was a free mode Phone, why do I still have to pay? I thought this was a gift card, why do I still have to pay? I want to redeem multiple Mode Phone gift codes, can I use more than one gift code at a time? I have already redeemed the gift on Current, when will I receive my gift card? I didn't mean to redeem this code, can I get a refund? I have already redeemed the gift on Current, when will I receive my gift code? I want to redeem multiple Mode Phone gift codes, can I use more than one gift code at a time?
