I am aware of this case, and I think this is a total knock off, sure would be nice if you had the TM but there is no doubt about it you were knocked off and it was known at the time. The fact you don't have a TM is valid but not totally since you were the first person to be using it and they have not only just added a hyphen to copy your name they knocked off the idea too or at least came as close as you can... way too close to accept.
This is a total bad faith rip off of an idea and name knock off by just adding a - LOL plus they regged the .co.uk extension same as your name without the hyphen.
When the regged the name they would have know about your site and idea. buzz me if you need my help.
