I received this message as well and, in the beginning, totally believed it. But more in-depth research has shown me that it is a hoax, sadly. However much we would all like to have 600, 000 british pounds in our pocket, sadly it won't happen through this "company". I tried phoning, but got nothing. I would disregard this email if you get it. Waste of time and, if you send your information, you're probably screwed. Identity theft is amond us these days. This is just one of the ways they get us.
Hope that helped!
