Help my code is no longer valid


So I purchased this offer “Free RAZE Energy Sample Pack (USA Only)” from Sweatcoin. Sweatcoin sent me a code so I went to the website to purchase the Samples. I entered my code and put in my bank account information and clicked checkout. But I noticed I entered the wrong expiration date of my card so I refreshed the page to try again. But then it said my code was invalid. I thought my fault I shouldn’t have refreshed so I tried to go purchase the code a second time but it said offer valid once per user. Is there a way you can send me another code please? My username is Serenity17 and my name is Daniel Cardenas.

Thanks in advanced for your help,
Daniel Cardenas
