As my father and uncle are both barristers then yes, I think what you are in fact referring to is defamation and that any statement must be proven to be false, whereas i can tell you that my points are factual. WWW have you ever heard of the OFT?
Off you toddle to your computer on which you spend half your life espousing your 'coveted' knowledge on sitting in a tube in the sky all day...great. You probably eat sausages with your fry up at your working class semi-detached.
I can list all the points in their brochure that are factually incorrect- there is nothing libellous in that. Unless of course the cartel here who has decided that BCFT is 'excellent' don't want their friends to hear it.
