Anyone tell me how do I extract someone's btc address from a payment they sent?

I have the TX ID
And when I go into the 100s of confirmation
how do I work out which was the btc send address.

I want to issue a customer refund but their playing hard ball & won't tell me.

Look up the txid on blockchain.info or other explorers. The sending address is usually at the left.
For example in this transaction (it's not mine) the sending address is 15HwcWAnHS44smDjfjYDw4P49YcGnBjcDK. You might find more than one sending address.

Edit:
If you're sending refund to someone you should have them tell you their address and not just send the bitcoins back to where they came from. The person you're refunding to might have used a service similar to coinbase that uses other addresses to send bitcoins. Someone got a problem with this exact thing here.
If they won't tell you anything about their address then it's their loss.

go to any blockexplorer (i.e. https://blockchain.info/) and put the transaction id in the search form. It will print out the sending and receiving addresses.
Hope it helped.

  I'm inclined to agree.
