I was interested in the services offered by duales because I periodically need to send money to Cuba. The registration procedure is quite confusing, for the following reasons: The second surname field is mandatory, and not everyone has a second surname. Special characters, like "ñ", and probably accented vocals, are considered non-alphabetical and are not accepted. These problems make unsure that a money transfer can succeed, since they potentially prevent correct identification of sender and/or beneficiary. For the above mentioned reasons, I preferred to wait that other, currently out-of-order, payment methods, are available again, since duales seems to be a not completely mature website.
