I'm very satisfied indeed with the service. Have made 2 successful payments to the US from UK. The process is all online including documentation of identity. First time, I had some questions and customer service responded to my emails promptly. Second time, there was an issue at the US bank. This was a bank issue as it turned out. Not a Transferwise problem at all. Transferwise Customer Service handled the issue exceedingly well. Again, everything was sorted out by email. They retransmitted the US funds and all went well in the end.
