Hello. Yesterday I mad two deposits to my wallet. One for $180 and another for $97. I then sent $271 to a friends address. 5 minutes Later I recieved a duplicate payment of $97 creating a double spend. This left my transaction of $271 unconformed. Can someone me please help me out? Blockchain.info was no help whatsoever. Is there anyway I can undo the transaction ? It's been over 50 hours and 0 conformations. Here is the hash https://blockchain.info/tx/3803ef67dc603ca2c80b9d0ea3bc928ec999b9d22b287db2a663ba3aa5856e03

If someone could help I'd be glad to donate
