You can get a UK address and sue them. When you win you'll get a judgement against them for the money they owe you. I don't know how easy it is to hold their hands to the fire in order to force them to make good on the court order. Good luck, lots of instructions out there. Don't let them get away with this. There is no good reason why they can't just be honest with people. People understand shit happens, but they don't get it. Their silence speaks much louder than any bad news. It speaks of deceit and malicious intent.
