XBOX GAME PASS DEAL

Yesterday i was checking my account, and i saw an xbox game pass 3 months subscription. I quickly deleted it because i was thinking that it was my old subscription that i made last year. After doing that my brother called me and said that his game pass vanished. It was a deal and to renew it it asks me the full price even tough my brother only paid it 1 euro. What can i do to renew the game pass?
