I just got a reply:
Hello,
It appears your transaction was rejected by the bitcoin network. An unconfirmed transaction will eventually be accepted into a block by whichever mining pool mines the block, or the transaction will eventually be rejected by the bitcoin network after an estimated 48-72 hours. If a transaction is rejected the sending address or wallet will not see a transaction returning the bitcoin. This is because when a transaction is rejected by the bitcoin network it is as though the transaction was never created, so the intended outgoing funds will have never left the sending bitcoin address. Like all wallet providers, Blockchain.info has absolutely no control over the confirmation process, and cannot expedite transactions. This is always dependent upon the bitcoin network of miners, which we are not a part of. Funds remain with the sending party. You'll need to contact them to ask for a resend. Best of luck.
I do not still understand why i am unable to send fund while i do have in my purse clear fund.
Blockchain.info cannot help you. You have to figure out why that transaction is not confirming first before anything can be done about it. My guess is that the transactions was double spent so it cannot ever confirm.
Does it mean my balance got locked that wallet.There should be some way out to get my funds to another wallet.
How to fix this 'double spent'
