Sorry about that — annoying when a survey shows success but only pays 10 coins. First, check My Profile → Held Offers and Completed Offers History to confirm status. Because your reward is small (under 10,000 coins), it’s usually an offer‑wall issue and we can’t auto‑release it here. Please contact the offer provider (support links on our FAQ: https://gain.gg/faq) and include the survey name, provider, reward, timestamp and screenshots of the “completed” page. If it was over 10,000 coins, open on‑site Support with those screenshots and we can try to help.
