My experience with both the UK and main headquaters has been nothing but good...if you dont mind my asking what did you buy from them, and what was the problem? Also in my opinion the N3 is a vast improvement over the C3.
EDIT: i am also waiting on the X3, have you any information on what the status of it actually is? because since it got announced again i have not heard anything.
I wanted to buy N3 but I did not want to pay with paypal since I had problems with paypal before. So long story short they offered me bank transfer so I asked some information related to it like name, address, bic and iban. Since then no email from them, not a single word. I guess they didn't want to sell it. If they replied to me with these information I would do the transfer on the moment I received the email but I didn't get anything from them. At the end I decided to move on and look for another DAP.
I wanted to get N3 asap and they even offered that student discount which was ended before I asked. Everything was nice except the last part. Well, I am quite sorry about that too but, there is nothing to do I guess.
EDIT: sorry I did forget your question about X3. All the information I get is coming from this thread:
I think soon we will have it in EU region. I am sure you can find answers to your questions in the thread.
