blockchain.info will refund to the sender after 36-48 hours or so if no miner is kind enough to include it in a block.
Troll much, or are you just misinformed?
You have a different answer?
Please utter it.

...without ANY explanation....
**** Thanks guys...
I really feel informed now...
The easiest option is to continue to wait. No, an "automatic refund" will never happen.
The only other option, which requires a good bit of technical skill, is for the sender to manually create a new transaction that spends the same inputs, but also includes a tx fee, and hope a miner picks that one up instead (which will then invalidate the original transaction).
Technically you could say the funds are still in the sender's wallet, but since the transaction has been broadcast, a miner could pick it up at any time and move the funds out to their intended destination address.
