How many BTC did you send what amount was the fee and what wallet did you use and what website is this. If you need help you going to have to give more info than that.
I'm really only worried about what was sent to Livecoin from Poloniex. I had asked this elsewhere and this is what I have.
About 18 hours ago I transferred from Poloniex to Livecoin yesterday. On Poloniex it shows that the transaction is completed, but according to Livecoin's support team there was no transaction made to my wallet. I have contacted Poloniex, but what can I do for this one?

You got 2 confirmations already. I don't know how many confirmations required at Livecoin but if it is like btc-e you'll get your coins when you got another confirmation probably. Blockchain is a bit loaded today, as soon as you get another confirmation your balance will be updated don't worry.
Well, this literally just happened because there was no trace of it before. Good news, thanks!
