Definitely need to make a deposit, I made a deposit through Webmoney, I can not withdraw money to it. Webmoney is not displayed as a way of withdrawal at the checkout. I wrote to the support service, they are silent for the second day already. Wait until I lose the bankroll)))
Their customer service is poor compared to others.
Last month I wrote them on similiar issue wanting to find out if I could cash out via Neteller.
The option was not there on withdrawal list but once I deposited it showed up. Found out this by trying as got fed up of waiting for them.
They eventually responded to me about with the info about two and half weeks after.
I made a deposit through Webmoney, but it is not on the list to withdraw funds.
PM me the details on how much you want to withdraw.
