I am new to bitcoin.  I have sent 2 seperate bitcoin payments to one vendor and other to myself changing wallets.  The vendor website shows the transaction as invalid, and shows unconfirmed in my wallet.  I sent my remaining coins to myself in a new wallet, and this still has not been confirmed going on 2 days now.  I was using blockchain as my wallet but read they are having major problems with confirmation.  I contacted the vendor and asked what the steps were for having the bitcoins returned to me since they show it as invalid.  I have not heard from them and wonder if anyone else has had this problem.  I though bitcoin was suppose to be a easy safe way to send money.  Seems to me to be very very insecure.
