Thanks Pinababy, I wasn't aware they were still sending out emails. I seem to have been removed from the list. That really is terrible!
I only deposited £600 by credit card, with the rest being by Neteller. Since they owe me £3700, i'm somewhat reluctant to claim my money back from the credit card company since it's only 16% of what i'm actually owed. If they do go bust, I will probably have to accept that route however.
