so i decided to go out and buy a few bottles of mountain dew. i come back and redeemed by codes. but then i noticed if one of the codes doesnt work you can just cal customer service and just tell them that your code didn't work. they'll want to get some information from you and they wont ask for the code you just tell them from which product you bought. just say the 24 pack one and you'll get a free 30 minutes without paying for it. Hope i helped out
