I had an issue like this regarding bank transfer which was also kind of urgent because my order was going to get cancelled if no payment was made, and I used their hotline, you can find the info on this page...

Thank you so much dude, so they do speak English via the hotline right? And may I ask if your problem solved? I mean do they allow you to extend the payment deadline or allow you to change the payment to BTC/LTC?
