For questions, feedback or corrections, write to:
cocupgradewiki@gmail.comWe usually reply within 24–48 hours.
Tell us the page, the hero, troop, spell, pet or building, your current and target level, any boosts you used, and what the upgrade screen shows without boosts. A screenshot helps us fix it faster.
We cannot help with account recovery, purchases or bans. For those, use Settings → Help and Support inside Clash of Clans.
