I second that, no offshore or companies with complex structure. The requirements of this bank change very fast. They also have problems now with transactions in USD.
The point is that two people in this thread claimed that they have accounts with CG Bank and everything has been fine untill now. Regarding Delta West Credit Bank I have not found yet any reviews.
Has anyone worked with http://www.dwcreditbank.com/ ? They seem very similar to CG Bank. I have seen a couple of messages here, saying that they are fake, but I am not sure if they actually had real experience with the bank.
I got the following reply from Wirex: Availability of cards is in no way connected to the possibility of sending and receiving international bank transfers. SEPA and SWIFT are available right now, UK Fast Transfers will be added soon.
