Bought a bitcoin, sender said it was sent, not showing in blockchain or wallet. Where is it? So I bought a full btc off of localbitcoin with amazon giftcard code. 
I sent the code and clicked that payment was completed. 
It's been about 2 hours. About 1 hour since he said that he sent the btc. I'm wondering if I got ripped off? 
I'm not showing any transaction in the block chain and it's definitely not in my wallet. 
Please help? What's going on?
LocalBitcoins uses escrow. If you've released payment and not received the Bitcoin all you need to raise a dispute. If you've already finalised the purchase and the Bitcoin isn't in your LocalBitcoins wallet then there's very little that can be done.

To clarify: did the Bitcoin ever get credited to your LocalBitcoins wallet? If not, raise a dispute ASAP.

I've never had issues with LocalBitcoins but I've never ventured outside of escrow or used gift cards.
