Contact Quickseller or macbook-air to push your transaction to F2pool. You can also try submitting the transaction here, but I haven't actually see a successful attempt with that so it may or may not work.

If You Use A Blockchain.info Wallet
Wait.
It will stop being broadcasted in 30 hours. I learned that the hard way.

I'm getting a feeling that this was changed as I'm getting a transaction of mine rebroadcasted every day for about a week...
Also sorry for the necropost...

Hello, everybody,
The coins finally came thru. I really worried my ass off for nothing. I thought everyone was wrong about the "just wait" phrases. I thought this was a rare occurrence that could only happen to me, but about 50 hours later, the Coins came!!!!
Thanks a million though for everyone's help and input.

Actually, in this case it probably had nothing to do with Bitcoin directly, but rather with blockchain.info's implementation. Blockchain.info has been having some difficulties with transactions getting "stuck" the past few weeks. They've issued a statement about it:
https://blog.blockchain.com/2014/03/05/occasional-unconfirmed-transactions-are-being-addressed/
It appears it has been resolved, at least according to the update they published to that statement. But the point is, this appears to have been a blockchain.info problem, not a Bitcoin issue.

Is there any BTC masters out there that could help me with this for a fee? I would very very greatly appreciate it.
If you post the transaction id, I'm sure someone will help you. I'll check back here later today to see if you've posted it.

@976_BTC: We cannot help you without TXID or destination address of the transaction.

Hello,
This is my first post here. Hello to everyone.
I have the same unconfirmed, zero(0) confirmations transaction I sent from my blockchain wallet. I sent about $245 to ONE address. I sent it 48 hours ago. I read someone above stated that blockchain will return the coins after about 30 hours, so this is now starting to worry me bc everywhere I read it takes blockchain 30-48 hours approx. to get the coins back if a transaction stays unconfirmed.
Is there any BTC masters out there that could help me with this for a fee? I would very very greatly appreciate it.
Details-
- I sent around $245
- I afterwards sent a couple cents to the same address that I got the unconfirmed stuck transfer, and the couple cents went thru in less then an hour
- the wallet I'm sending it to has no way for me to check if there is any pending transfers.
- I used the recommended fees setting(the middle setting)
- the network propagation is very low at 0-1%
Thanks a million in advance for any help or thoughts.

If You Use A Blockchain.info Wallet
Don't.
It uses a non-standard Bitcoin that doesn't calculate correct minimum fees or minimum transactions amounts required by Bitcoin.
Many learned that the hard way.

As a TL;DR to my long post above: after removing a never-confirming transaction from your wallet to restore your balance, simply spend your whole wallet balance back to a new wallet address to be sure the old transaction is invalidated on the network.

well, it seems waiting really works 
just got all 3 tx at the same time confirmed.. crazy system, hope this works better as soon as btc is really mainstream

It will work fine if users include a reasonable transaction fee.
It will also work better if miners implement "child pays for parent". Such an enhancement would increase their profits and would solve problems like this.

so you are actually saying that I need to wait and do nothing, right? ;-)
then my first tx should be back in my wallet tomorrow morning... too bad the blockchain wallet does this from time to time, seems I will only use the custom tx instead of quick tx in the future (where I can adjust the fee by hand)
Does it mean it will be reversed and back in my wallet to spend if the tx was not confirmed within 30 hours?
What would happen if I would import the blockchain wallet data into bitcoin-qt and double spend the btc to get them back?
You have to wait for it to leave te memory pool, anyway, but in ~30 hours, it will be back in a Blockchain wallet.
