From their website:

We have never failed to help a client as long as they comply. It will work for you but if you feel it hasn't, it's probably because you are doing something incorrectly. That being the case, contact us as soon as possible and we will make sure you get onto the right track.
Seems like a scam to me, from that paragraph. They've dismissed all the clients it didn't help as "non-compliant" so that they can calculate their success rate as 100%. No legitimate treatment claims to work for 100% of people who try it.
Edited to add:
I shouldn't be so skeptical. This method might help some people, maybe even you. However, I'd try to find some third-party information about its success rates before I risked £129 (especially as I'm American and the exchange rate sucks right now).
