I wouldn't go anywhere near them, no number, no address and no company registration number. The other thing that sets alarm bells ringing is the testimonials, I work in marketing so I know a thing or two about testimonials and these are all to alike, plus anyone with half a brain would want to use the names of their star signings, it doesn't make sense to keep them anonymous especially due to "marketing contract."
The other thing that concerned me was this "We do not refund you your money if you have used the bat and broken it yourself, all our bats are of exceptional quality and will only break if you are using a cheap ball or have not timed the ball well." Now correct me if I'm wrong, but a how are they going to know if you've misstimed a shot (unless it comes with a hidden camera - now there's an idea) and also are not bats designed to be able to withstand the odd misstimed shot?
