Please hellp me!! Im a begginer and im having a problem ((

I registered on a wesite, paymium.com, and add 0.8 BTC on my account. Then, i made a transcation to my adress in a store website.

The transaction shows up in Paymium, and my BTC are certainly not here anymore !! :p But there are not on the other website either !! But it said transactions need 3 confirmations and on the internet, it says it should last 10min to 3 hour max, but its been 6 hours and nothing happens !! When I click on the adress i got this :

https://blockchain.info/address/1Lq5Cqbmk7cEgrEYgd19hSMyiNvrjoBkuW

Saying No transaction has been done yet or treated by network !!

But paymium does confirm my transaction had been done to that adress..
So please what should i do ?

Thanks a lot for ALL yuour advices
