Thanks Danny, I am a bit of a novice with bitcoin. My provider (coincorner) did a test for me and received multiple confirmations of the transaction. I do have the send address in both instances and I also have what I assume is the send ID ( long alphanumeric code) from my history file in CoinCorner. However my friend says only the btc sent to the previous receive address after it changed has not arrived in his wallet.

I am not sure of the security implications of sharing the target receive addresses on this forum. But if it is not an issue I can do so.

Thanks

I have sent some money via bitcoin to a friend who is currently staying in China. I used CoinCorner.com to buy my BTC and then sent them to a wallet address supplied by my friend from a local online provider. The first payment was received, no problem. I then sent a second payment two days later to the same wallet address (and confirmed by coincorner.com). But my friend's provider had subsequently allocated him a new receive wallet address leaving him unable to access the money in the original wallet address. My friend emailed the contact at his service provider (Blockchain) and got this response: 'unfortunately we are unable to assist as a third party between buyers and third parties. Please contact the exchange or merchant you were working with in order to resolve the issue'. So armed with only the original receive wallet address how can we go about recovering the second payment? Many thanks
