Hi jamieprec1979,
I too took Kensington to court over default charges, I think I was one of the first.
Anyway to cut a very long story short - I got my money back, after a year, an attempt to strike out my claim, adding their solicitors costs to my account, and them not meeting any deadlines set by the court.
I would suggest try the FSA first and see what happens - if that fails go the legal route, but be prepared for a long hard fight. I estimate Kensington spent £3000 defending a £450 claim!!!
Just one last thing, they did orginally offer settle but with confidentiality - when I said no to confidentiality it all kicked off.
Full Story here;-
Yes Yes Yes **first Win From Kensington!!!!!!!!!!**
Good Luck
