I keep receiving a deposit of 0.002 BTC to my wallet which stays unconfirmed for several days, then I get this message from blockchain - and of course the deposit disappears, only to be re-deposited after a couple of days, again staying unconfirmed and failing. This has repeated itself 5 or six times. my question is - 1) how can I get this confirmed and 2) if 1 is not doable, how can I stop it.
Any suggestions.

This is the message I get: Transaction Confirmation Failed

A transaction made through Blockchain.info has been removed from our database because it was taking a long time to be included in a block.

Any funds have been returned to your wallet and you can now spend the coins again. Please consider including a larger fee in future transactions.
