GMM giveaway

Hello,

can someone tell me how I get my GMM giveaway. I received this notice below but their Twitter "Whispers"  said they have blocked me, so I could not provide them my information? Who or how do I contact them?

Hey there, congrats on your GMM giveaway! Please provide us your console and your gamertag/psn/EA app or Steam Name! Thank you for tuning into Good Morning.
