Coins lost after deposited to Cryptsy ??????

[nzminer]

My friend deposited 1K of mintcoin into cryptsy and it never showed up there.
After making an enquiry to cryptsy their reply was "the transaction ID does not show in either our wallet or the block explorer.
You will need to investigate the source of the transaction and ensure it was sent to the correct chain"

What on earth does this mean?
How can the coins vanish nowhere, when it was sent to the address that they provided?

Luckily for you, 1k mintcoin is only about 2 cents.
