Weird unconfirmed (3 days) transactions appearing in my wallet

[Minsk]

I have these 4 very strange transactions in my wallet that have been unconfirmed for well over 3 days now, and when I try to look them up by transaction ID on blockchain.info, they cannot be found. Anyone know what is going on with that?

Heres is an example, I have 4 of them total.

For the past few days, someone (from bitwars) keep spamming  the network by sending tons of 1-satoshi outputs to random addresses, with way below min fee.

Such tx will never be included in a block, and now all nodes have already dropped the tx and thus you can't find it on bc.i anymore.

Hi
On 25th of Jan. I have transferred a small amount of bitcoins to a member
Wallet. The transaction went through but the Member says that he has
not received the bitcoins and when I checked my transactions details
it shows with a RED ARROW and the bitcoins have been deducted
from my account  Since the member never received it and it has been deducted
from my account, how do I claim it back to my account.
Thanks in advance for the advice.
