To finish this discussion, we want to state the following:

The allegations of us being scam are false and misleading. The guy stating so, is a pure fraud and a scam. To make the story short:
First, the technical issues about which everyone is worried are related to the status “completed” as the transaction has passed the wallet interface, but was stopped before being broadcasted (and the status was not reflected in the user interface). This is was a technical issue, which now has been solved.

Second, there are complaints regarding this client (however we cannot comment more on them due to privacy issues as I have already got a negative feedback for it), hence we will be able to unfreeze the funds either the complaints will be solved or we will receive required documents. On the other hand, this person has only created a forum account to discredit us and has provided fake documents and is only telling a small part of the full story.

One more time, we have more than 100,000 happy clients and we are working hard to expand our services and I believe that an incident with one scammer trying to discredit and blackmail us will be understood as an accident which can happen for everyone. It has taught us a lesson, that in addition to reliable, fast and low-cost services, we have to work even harder to ensure the trust of our clients.
