Do you have a transaction-ID? What are the wallet-addresses of both (pool and receiver). With that information we could check the current (official!) blockchain against that ( http://mooncoin.info/abe/chain/Mooncoin ). Did you contact the pool-owners about that? If so, what did they respond?

And read this post, regarding mooncoinpool.com and the new fork: https://bitcointalk.org/index.php?topic=389403.msg6101022;topicseen#msg6101022 - as well as the following posts, dealing with that concern.
