I have around 30$ in several tokens and cannot withdraw them as the fees are higher than the balances. But the email I got didn't talk about paying any fees. They also don't give me a deadline to withdraw:
No deadline has currently been set for customers to withdraw funds, but we strongly recommend that you complete this as quickly as possible, as a withdrawal deadline may be set by the liquidators at some point in the future.
As I said to @bengy, they appear to have different sets of emails. Strange company.
